Using `>` for lambda syntax excludes tuple comparison

[brthornbury]

The situation where you want to compare tuples and assign a boolean becomes impossible.

# Makes a lambda
a = (x,y) > (2,3)

in can be currently used as an alternative to >. This is a bug but it is not so bad.

# Makes a lambda
a = (x,y) in x + y
