Fellow monks,

I have an interesting dillema. Due to forces outside of my control, I have to work with existing code which has something like:

use myPackage;
myPackage::foo();
myPackage::bar();

[download]

The problem is that in my environment, I cannot have the obsolete myPackage module because it has been replaced with myNewPackage module. The nice thing is that this myNewPackage has almost a one to one mapping of function names (and their functionality). So, I was hoping to write my own dummy myPackage which would actually do something like:
package myPackage;

use strict;
use myNewPackage;

# magically convert myNewPackage::* to myPackage()::*
# except for one function where myNewPackage::bar() needs to actually 
+provide myPackage::old_bas()

it seems like something like this should be possible, but I cannot think of an easy way to do it short of actually going through every function and creating an explicit mapping like (pseudocode):
sub myPackage::a {
    return myNewPackage::a(@_);
}

sub myPackage::b {
    return myNewPackage::b(@_);
}

sub myPackage::old_bas {
    return myNewPackage::bar(@_);
}

Does anyone have any good ideas for how to deal with this?

thanks as always!
