Perl::Critic::Policy::BuiltinFunctions::ProhibitStringyEval - Write eval { my $foo; bar($foo) } instead of eval "my $foo; bar($foo);".
eval { my $foo; bar($foo) }
eval "my $foo; bar($foo);"
This Policy is part of the core Perl::Critic distribution.
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
eval "print $foo"; #not ok eval {print $foo}; #ok
This Policy is not configurable except for the standard options.
