in reply to Shortcut operator for $a->{'b'}=$b if $b;
{ $hash{data} = $_ if defined ( local $_ = $something ); }
A simple if-block is not to be faulted but if you are going to use a single statement a large $something should come last; else it will obscure following logic.
With the above it is easy to forget to close a scope over the local.
Be well,
