Actually, it's having warnings on that causes this, not strict. This,

You can find full explanations of perl's warnings in the perldiag
manpage. If you wish, using the diagnostics pragma will output the
appropriate explanation with the warning. The reason for using an
actual scalar, rather than a one element slice can be found there. I'd
put it in here, but vim is giving me some pasting problems at the
moment...
