Use of guppylang.std namespace

[perlinm]

A lot of my files start with something like

from guppylang.std import angles, quantum

at the top. Aside from the minor annoyance that the variable name angles is taken, I generally to be (at least a bit) more explicit with namespace. However, the following does not seem to work:

from guppylang import std  # OR: import guppylang.std as std
...
std.angles.pi

Can we expose std.angles (and std.quantum etc.) by adding them to guppylang/std/__init__.py? Is there some other way to be explicit about namespace?

The same goes for guppyland.std.builtins, as I will definitely forget that result is taken as a variable name 🙃

Importing submodules in std/__init__.py causes circular imports

I would recommend using as aliases to manage namespaces rather than long absolute paths

from guppylang.std import angles as ang

ang.pi
