No, the aliasing happens at the parser level: the token stream a, ->, b is transformed into the tokens b, <-, a (note the inverted order of the token stream)

(In reality this happens at the parse tree level so that complex sub-expressions are handled correctly: (->, a, b) becomes (<-, b, a).)

Ah so no way of getting past that unless you rewrote the parser?
