in reply to Re^2: map problem
in thread map problem
The code with the semi-colon
- has an unambiguous effect (not a valid hash constructor),
- has an unambiguous purpose (coder obviously doing something to appease the compiler), and
- is idiomatic.
{ ("x$_" => 1) } is still a valid hash constructor, and it's not clear that the parens are required, so it's not as clear as it could be.
