tinne updated GROOVY-7935:
--------------------------
Description:
The Groovy [style guide|http://groovy-lang.org/style-guide.html] says, "...
Groovy doesn’t allow you to remove parentheses. [...] for nested method calls
or on the right-hand side of an assignment, you can’t omit them there."
Then, a code fragment is given, where just this works.
{noformat}
def foo(n) { n }
println foo 1 // won't work, as documented
def m = foo 1 // this works indeed!
{noformat}
Further more, I could not find any examples, where this would not work, neither
with comma separated parameter lists nor with infix computations nor closures.
So I guess it is just a documentation bug and right-hand side parens removal
support has been added.
