Perl::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
This Policy is not configurable except for the standard options.
