Chapter 6 of Camel3 says:
foo; # like foo() if sub foo predeclared, else bareword "foo"
One of my scripts is similar to the following:
use CGI;
my $q = new CGI;
print $q->p "hello world";
To my surprise the above code snipped fails. It also fails if I replace 'use' with 'require'. But if I surround the arguments to p with parentheses then it works, i.e.,
use CGI;
my $q = new CGI;
print $q->p("hello world");
If for whatever reasons one wanted to predeclare a member function of a CGI object how would one do that? Clearly, perl does not consider 'use' or 'require' to constitute a predeclaration.
