Recipe 1.8: Using Literal Values as Objects

Last Updated: Sep 8, 2003 Status: Draft

Problem:  

You want to use a literal value as if it were an object.

Solution:  

Just do it:

print "a literal string".length;

print { key1 => 'val1' }.keys;

Discussion:

A literal value is nothing more than a specific (constant) instance of a builtin type or class; as such, you may call methods on literal values in the same manner as you call them on any other builtin types.
