No, otherwise CGI.pm and tons of other stuff would never work.

Consider the following program:
$_ = 'sub foo { print "Hello World\n" }';
eval $_;
foo();
foo() is not defined a compile-time, but it's still a perfectly valid
program. Because of this, perl -c cannot check the call to foo() at
compile-time.
Thinking of perl -c as a "compiler" is a bit of a misnomer. Just for kicks,
wrap the code above in a BEGIN { } block and run perl -c on it. See what I
mean?

No way! :~)
