It is said that just because you find something useful is no reason alone to publish it. There is perhaps no better example than this module, which bills itself as an attempt to merge printf and sprintf, while saving typing and adding safety checks.
Use of this module will lead to hard to read, hard to debug code that is just not suitable for group projects, and the test failure record of this module on cpantesters is nothing short of impressive... in a bad way....
The author, I am sure, finds this helpful but for the rest of us? It is totally a useless waste of a top-level namespace.
