Re^4: Announcing Perl-Critic-0.14

Conclusion: Always assign something in a my declaration?

The following works as expected.

my $i = $bar ? 123 : undef;

And yeah, that's really weird.

Conclusion: Always assign something in a `my` declaration? More precisely: make sure an assignment with a `my` on the left-hand side is never conditional. Makeshifts last the longest.	[reply] [d/l] [select]

It's not about the assignment. It's that my() should never be conditional. `my $foo if $bar` is just as bad for the same reason. You're just not likely to write that because it looks funny. `my $foo ... for ...` is probably also just as bad. The statement modifier form allows the my() to declare the variable for use by all following statements in that scope. ⠤⠤ ⠙⠊⠕⠞⠁⠇⠑⠧⠊	[reply] [d/l] [select]

Always assign something in a my declaration? I think it boils down to: Never modify a lexical unless the my() was executed during the current execution of the enclosing block.	[reply]
