I agree that it is worrisome.

You could make the same argument about dereferencing. How about it?
You want to write
$n_elements = @$aref;
but if you are using "strict refs" you have to put instead:
$n_elements = ref($aref) ? @$aref : .... ;
or you risk a run-time error.
But presumably you don't do this, and you don't let it prevent you
from using "strict refs" either. So why are the two situations
different? (This is not a rhetorical question.)
