In what way did it "not work"? What did it actually do?
Whenever arguments start being finicky, its a good idea to print them back out to make sure you're putting in what you think you are. Try
to make sure its doing what you think it is.
eval is definitely not "the way" to do this. That it's not working suggests to me the input might have things in it which are unexpected and eval works around by quote-splitting or some such.

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.
