Eric Milles updated GROOVY-5773:
--------------------------------
Description: In Groovy if you see x==\~y and x == \~y you can can get a
problem, because it is easy to oversee the space in between, changing the
meaning of the compare. The problem is toped by x != \~y being the negation of
x == \~y, but there is no negation for ==\~. This issue is therefore asking for
a replacement of the operators ==\~ and =\~ in a way that allows the negation
too and is still readable. For this no unary operator symbol should follow the
equals if equals is kept. (was: In Groovy if you see x==~y and x == ~y you can
