i tried some other projects for my current challenge - either
resulting in poor performance or a headache &#59;)

This library seems af it's been made for my challenge:
ParseTime/Expression: irrelevant - EvaltuationTime/Item: minimal
(I'm building some kind of DataView just for objects which dictates the need of FilterExpressions and calculated Columns)

Works like a charm! Thank You!IInvocationMon, 23 Jan 2012 16:27:27 GMTReviewed: Flee-0.9.26.0 (Jan 23, 2012) 20120123042727Phttp://flee.codeplex.com/releases/view/28952#ReviewBy-S397Rated 5 Stars (out of 5) - The best library. Fast and easy to integrate. I use it 2 years.

Flee's strength may not be its parser, but the fact that it compiles the parsed expression into IL byte code for optimal performances. 
I suggest that you reproduce the demo application with your own parser, and post the results. 
I'd be amazed if you can match its perfs.

Fast and flexible too - many thanks.MikePeltonSat, 27 Nov 2010 11:06:46 GMTReviewed: Flee-0.9.26.0 (Nov 27, 2010) 20101127110646Ahttp://flee.codeplex.com/releases/view/28952#ReviewBy-ArturMustafinRated 1 Stars (out of 5) - Not very readable, really, and absolutely it is not lightweight.

Using my project you can create you own parser in seconds, and, yes, it is REALLY lightweight, and, it's only ~ 19K for debug .NET version. You can try some demos out of the box as Windows Forms math demo as well as excel demo.

Using my project you can create you own parser in seconds,
it is REALLY lightweight, and, yes, it will be source compatible with Silverlight 4, if you request it to, it is really lightweight - it's ~ 19K for .NET version. You can try it out as Windows Forms math demo as well as excel demo.

Easy to implement&#59;
Fast&#59;
Was the answer to a serious challenge I faced while working on a program for intelligent assemblies&#59;
Probably saved my *.
Great great work.aj100Tue, 15 Jun 2010 17:07:56 GMTReviewed: Flee-0.9.26.0 (jun 15, 2010) 20100615050756Phttp://flee.codeplex.com/releases/view/28952#ReviewBy-PistolPeteRated 5 Stars (out of 5) - This is the best expression eval library for .NETPistolPeteThu, 27 May 2010 20:36:35 GMTReviewed: Flee-0.9.26.0 (May 27, 2010) 20100527083635Phttp://flee.codeplex.com/releases/view/28952#ReviewBy-redwards1966Rated 5 Stars (out of 5) - Great library.

I compared FLEE with other expression evaluators (by evaluating an expression containing one string and one decimal comparison 1 million times with different values) and it was way ahead of anything else. 

Here's the comparison result:
12 times faster than Linq DynamicExpression,
6 times faster than NCalc,
3 times faster than Spring.net Expression evaluatorchikakWed, 10 Feb 2010 15:29:23 GMTReviewed: Flee-0.9.26.0 (Feb 10, 2010) 20100210032923Phttp://flee.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=28952#ReviewBy-chikakRated 5 Stars (out of 5) - Great work!

It would be nice to see some syntax customization capabilities. For example, I need to use "mod" operator instead of "%" or even some unicode characters as an operator (x² instead of x^2, √2 instead of x^0.5, etc).
