--TEST--
Generics extension: generic-like syntax inside strings and heredocs/nowdocs is not stripped
--DESCRIPTION--
Tests that the strip_generics() function does not modify content inside:
  - Single-quoted strings
  - Double-quoted strings
  - Heredoc strings
  - Nowdoc strings
Any <...> syntax appearing inside these contexts must be preserved verbatim.
