COR040 use-all

warning enabled by default

A use statement imports everything (no only: list).

Why

Without only: every public entity of the module enters the scope: names collide or shadow local ones silently, and a reader cannot tell where a name comes from. only: makes the dependency explicit and keeps scopes small.

Reported

use penf

Preferred

use penf, only: R8P, I4P

Suppressing

For one occurrence, with the reason on the same line (or alone on the line before the statement):

! fobis: ignore[COR040] <why this occurrence is fine>

For the whole project, ignore = COR040 in the fobos [lint] section.
