Oh, about the guy I thought I got to do the student competition: turns out ambiguity was just being annoying... he said something along the lines of "I think I'll pass" which I interpreted as "passing" the competition (i.e. doing well), when he actually meant he'll pass up the opportunity.
@Feeds What?! A class? (At first, I thought that was Uriel)
I am trying to parse APL expressions using ANTLR, It is sort of APL source code parser. It parse normal characters but fails to parse special symbols(like '←')
expression = N←0
Lexer
/* Lexer Tokens. */
NUMBER:
(DIGIT)+ ( '.' (DIGIT)+ )?;
ASSIGN:
'←'

DIGIT :
[0-9]

To get a simple vector result, stick a ∊ on the very left.
