A::x_2         # -> 2
(\&A::x_2)->() # -> 2.03

# Functions with parameters not cached:
A::y_1 .5  # -> 1.5
A::y_2 .5  # -> 2.53
```

# DESCRIPTION

A Perl program consists of packages, globals, subroutines, lists, and scalars. That is, it is simply data that, unlike a C program, can be “changed on the fly.”

Thus, this module provides convenient functions for transforming all these entities, as well as maintaining their integrity.

# SUBROUTINES

## aroundsub ($pkg, $re, $around)

Wraps the functions in the package in the specified regular sequence.

The package may not be specified for the current:

	# Perl cached subroutines with prototype "()" in main:: as constant. aroundsub should be applied in a BEGIN block to avoid this:
	A::x_2         # -> 2
	(\&A::x_2)->() # -> 2.03
	
	# Functions with parameters not cached:
	A::y_1 .5  # -> 1.5
