Description

MVEL is hanging when trying to compile the following expression:

source = "abc"; pat = "abc"; source ~= pat

It does NOT hang when compiling:

pat = "abc"; "abc" ~= pat

It also gives duplicate variable exception when compiling:

String source = "abc"; String pat = "abc"; source ~= pat

I'm committing failing test cases to 1.3 branch.
