DESCRIPTION

MooseX::Mangle provides some simple sugar for common usages of around. Oftentimes all that is needed is to adjust the argument list or returned values of a method, but using around directly for this can be tedious. This module exports a few subroutines which make this a bit easier.

EXPORTS

mangle_args METHOD_NAME CODE

Applies an around method modifier to METHOD_NAME, using CODE to mangle the argument list. CODE is called as a method, and additionally receives the arguments passed to the method; it should return the list of arguments to actually pass to the method.

mangle_return METHOD_NAME CODE

Applies an around method modifier to METHOD_NAME, using CODE to mangle the returned values. CODE is called as a method, and additionally receives the values returned by the method; it should return the list of values to actually return.

guard METHOD_NAME CODE

Provides a requirement that must be satisfied in order for METHOD_NAME to be called. CODE is called as a method, receiving the arguments passed to the method. If CODE returns true, the method is called as normal, otherwise undef is returned without the original method being called at all.

BUGS

No known bugs.

Suggestions for more modifiers are always welcome, though.
