Recipe 2.13: Calling Methods Indirectly

Last Updated: Sep 8, 2003 Status: Draft

Problem:  

You want to call a method of an object or class, but the name of the method won't be known until runtime.

Solution:  

Use indirect syntax, possibly with a check to CAN to be safe:

my $method = "foo";
$obj.$method if $obj.CAN.$method;

MyClass.$method if MyClass.CAN.$method;

Discussion:

Issue: Any problems with $obj.$foo.$bar?
