IO::Select

Native Rust implementation built into the interpreter. Runtime: P5. See original documentation for the full Perl reference.

IO::Select objects are blessed HV refs internally storing:

• __fds: an AV ref mapping fd_number -> stored handle SV
• __count: integer count of registered handles

Mirrors the pp.rs implementation using P5Interp/P5Sv types.
