Can one return bytes or bytearray from task decorated function? about belay

I like the second approach.

Currently we don't support bytearrays (we do support bytes, however). Belay works on the symmetry of repr serialization and ast.literal_eval deserialization to work. However, I just noticed that ast.literal_eval('b"\x00"') doesn't work (literal_eval doesn't like null bytes), so maybe we should swap it out with a more powerful parser.

EDIT: ok the null byte thing was an escaping issue, however, I'll look into supporting bytearrays

[BrianPugh]

If we swap out ast.literal_eval with the unsafe eval, we can support bytearrays (as well as any other class who's repr perfectly matches it's constructor). However, this then allows arbitrary execution from a remote device, which doesn't sound like a great idea.

Maybe we can set an "unsafe parsing" boolean that then sets whether or not to use ast.literal_eval vs eval. Thoughts?

this should be pretty easy; i'll really try to get to this and the pydantic stuff soon.

closing this issue, further discussion can be done in the PR. I'll be merging and releasing once CI is sorted out (it's like 50% sorted out as of right now).
