I've noticed something interesting in C++ programming. I've always done tricky stuff with pointers and references to have functions deal with arrays. Doing exercises again out of a C++ book has shown me an easier way, I didn't even know was there. It's weird to me.
When dealing with arrays, it... (4 Replies)

Perl::Critic::Policy::BuiltinFunctions::ProhibitStringyEUser3Contributed Perl DocumePerl::Critic::Policy::BuiltinFunctions::ProhibitStringyEval(3)NAME
Perl::Critic::Policy::BuiltinFunctions::ProhibitStringyEval - Write "eval { my $foo; bar($foo) }" instead of "eval "my $foo; bar($foo);"".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
The string form of "eval" is recompiled every time it is executed, whereas the block form is only compiled once. Also, the string form
doesn't give compile-time warnings.
eval "print $foo"; # not ok
eval {print $foo}; # ok
CONFIGURATION
There is an "allow_includes" boolean option for this Policy. If set, then strings that look like they only include a single "use" or
"require" statement (with the possible following statement that consists of a single number) are allowed. With this option set, the
following are flagged as indicated:
eval 'use Foo'; # ok
eval 'require Foo'; # ok
eval "use $thingy;"; # ok
eval "require $thingy;"; # ok
eval "use $thingy; 1;"; # ok
eval "require $thingy; 1;"; # ok
eval 'use Foo; blah;'; # still not ok
eval 'require Foo; 2; 1;'; # still not ok
eval 'use $thingy;'; # still not ok
eval 'no Foo'; # still not ok
If you don't understand why the number is allowed, see Perl::Critic::Policy::ErrorHandling::RequireCheckingReturnValueOfEval.
This option inspired by Ricardo SIGNES' Perl::Critic::Policy::Lax::ProhibitStringyEval::ExceptForRequire.
