COR050 missing-accessibility-statement

warning enabled by default

A module has no default accessibility statement (private or public).

Why

Without a default the module exports everything it declares or uses, including helpers and the entities of every module it uses. Start with private and mark the API public explicitly.

Reported

module grid
implicit none

Preferred

module grid
implicit none
private
public :: grid_t

Suppressing

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

! fobis: ignore[COR050] <why this occurrence is fine>

For the whole project, ignore = COR050 in the fobos [lint] section.

Equivalent

Fortitude rule C131 (see Lint Rules).
