There are tons of OS specific features that are both widely used and embedded into perl. This hasnt balkanized it onto one platform. And most of those features are UNIX specific. In fact as a solely NT user I come across UNIX specific code all the time, but it pretends to be portable when it isnt.

Also note that nothing in the OP's idea would change your current practice. Nothing would _force_ you to use the feature.
