465 | # Because: |
466 | # 1) This is a *very* rarely used function, and the deptree is large |
467 | # enough already as it is |
468 | # |
469 | # 2) (more importantly) Our tooling is utter shit in this area. There |
470 | # is no comprehensive support for UNC paths in PathTools and there |
471 | # are also various small bugs in representation across different |
472 | # path-manipulation CPAN offerings. |
473 | # |
474 | # Since this routine is strictly used for logical path processing (it |
475 | # *must* be able to work with not-yet-existing paths), use this seemingly |
476 | # simple but I *think* complete implementation to feed to other consumers |
477 | # |
478 | # If bugs are ever uncovered in this routine, *YOU ARE URGED TO RESIST* |
479 | # the impulse to bring in an external dependency. During runtime there |
480 | # is exactly one spot that could potentially maybe once in a blue moon |
481 | # use this function. Keep it lean. |
