Description

This is perfectly valid PHP, since function and class names are case insensitive. However I think it would be good form to enforce case-sensitivity for callables.

Contributor guide

Research direction
Examine Psalm's callable type resolution to find where case insensitivity occurs, then add a strict comparison to enforce case sensitivity.
