Can't use variable's name starting with 'e'

[zeFresk]

Hello,

I found your project while trying to program the same thing and I was so impressed that I started using it immediately !

However, I found what I think is not an expected behavior :
Because of the priority of constants over variables the parser fail to parse the expression popsize >= elite with the message Parsing failed at lite.

It is possible to not use such names but I thought you may be interested in knowing that.
