":i (->)" doesn't work

[SamB]

Prelude> :i (->)
<interactive>:1:1: parse error on input `->'

I hope that's clear enough for you ;-).

Also fails for me in 6.6.1. Since :i [] works but not :i ([]) (should this be true?), I tried :i -> and :i ((->)) and :i (a->b) ... none of which worked.

[] isn't an infix name, so I wouldn't really expect :i ([]) to work. (([]) is valid as an expression, but not as a name.)

Fixed locally; will add a test and push later.

Pushed.
