Module module 

A Python module mounted as an environment (spec: Environment Mounts, py=python:./helpers.py; Environment Commands): the module’s functions as commands under the mount’s alias, with the native framing. The input is the first positional parameter unless $_ places it among the operands or in an option’s value (py:round(2) is round(x, 2), py:sub("^get_"; ""; $_) is sub("^get_", "", x), py:f(--data=$_) is f(data=x)); the operands are the positional arguments in order, the options the keyword arguments; a raised exception is a failed call, null after | and a refusal after @|, where the one call over the stream answers one thread per returned value. The module is imported once at mount time, from a file or by its import path, and its synopses are read from the functions’ signatures as a reflected library’s are. An environment reaches outside the query by definition, so nothing in the module is withheld for reading a file.
