Currently, the ANTLR grammar, when given to ANTLR3, complains with the error:

error(204): pony.g:162:53: duplicate token type '-~' when collapsing subrule into set

It appears that this is due to TK_MINUS_TILDE_NEW being output as simply '-~', and not, say, as TK_LPAREN_NEW is (as a newline, followed by the token). Its definition in the ANTLR grammar currently is identical to TK_MINUS_TILDEs.
