> Currently, in Jexl, the only way to add a functionality is to define a variable.
> Typically this is done in a separate environment... e.g. in jelly's j:new, j:set or...
> Using this, one can define, say, "a" then invoke "a.doSomething(withThat)".
> It would be nice to allow adding methods, e.g. "doSomething" to be invoked without any
object.
> This way I could just say "doSomething".
> Examples of usage include:
> - add some mathematical functions to make jexl full featured mathematically (e.g. "abs",
"exp", 
> "atan")
> - add some "general purpose utilitites" (e.g. "tokenize(aString)", "toString(xx)", or

> "relativeUrl(baseUrl, relPath)")
> - thereby become more compatible with JSP (i've been told)
> This should promote general usage of such functions availability.
> In some situations this would help a lot. For example in maven where I too often still
see 
> srcFile="${baseDIr+pathToResource}" which prevents any overridability.
