Module inline 

Refactoring and modernization helpers. Subroutine inlining for Perl code.

Provides text-based subroutine inlining that replaces a call site with the function’s body after substituting formal parameters with the actual arguments from the call.

Limitations

This is a text-pattern implementation. It does not build a full AST and therefore relies on heuristics for:

• Parameter extraction (assumes my ($a, $b, …) = @_; pattern)
• Return detection (counts return keywords)
• Recursion detection (looks for the sub name inside the body)
• Side-effect detection (looks for print, warn, die, open, close, write, read, seek, sysread, syswrite)

Functions that do not follow these conventions may not be inlined correctly. The safe defaults are to reject when uncertain (recursion, large body, multiple returns) and to warn when side effects are detected.
