7. Enhance source code semantics

Overview

Leverage elements from recent Fortran standards to further improve the clarity and intent of code statements beyond previous recommendations.

Checks

• PWR003: Explicitly declare pure functions.

• PWR072: Explicitly declare the 'save' attribute or split the variable initialization to prevent unintended behavior.

• Planned: Prefer variable initializations at declaration instead of data or block data statements.

• Planned: Add an explicit parameter attribute to constant variables.

• Planned: Explicitly declare elemental functions.
