superfluous-save (MOD051)

Fix is always available.

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 unnecessary save statements and qualifiers

Why is this bad?

Since Fortran 2008, module variables are implicitly saved. Save statements and attributes can safely be removed.

Example

module example
    integer, save :: a
end module example

or

module example
    save

    integer :: a
end module example

Use instead:

module example
    integer :: a
end module example
