- name: gc
- description: use module gc
- command-line: –withmod-gc
- command-line for negation: –withoutmod-gc
- option type: boolean option
- default: True

Use the ‘gc’ module. This module is expected to be working and is included by default. Note that since the gc module is highly implementation specific, it contains only the `collect` function in PyPy, which forces a collection when compiled with the framework or with Boehm.
