Yes, several.

You can check yourself with prototype

From the docs:

If FUNCTION is a string starting with CORE:: , the rest is taken as a name for a Perl builtin.

If the builtin's arguments cannot be adequately expressed by a prototype (such as system), prototype returns undef, because the builtin does not really behave like a Perl function.

Otherwise, the string describing the equivalent prototype is returned.
