Is there a way to test if Perl code is valid, without having the Perl code you want to validate, affect the rest of the script?
No. Consider: 
BEGIN {
    my $p = rand() < .5 ? '$' : '';
    eval "sub foo($p) {1;}";
}

foo / 1;

Valid or not? Without executing the begin block, impossible to answer. (It's valid if the prototype is empty, it's a syntax error otherwise.)
