keyword-reuse (S311)

This rule is unstable and in preview. The --preview flag is required for use.

This rule is turned on by default.

What it does

Checks for the use of keywords when naming variables, modules, functions, etc.

Why is this bad?

The reuse of keywords as identifiers can be confusing to readers, and may cause problems for some tools. Enforcing this rule can help maintain a consistent style.

Examples

module program

  implicit none (type, external)
  private

contains

  subroutine function(stop)
    integer, intent(in) :: stop
    print *, stop
  end subroutine function

end module program
