Thoughts on language-level configuration support?

[CTO]

On the one hand, I can 110% see why you want to reduce boilerplate
code and provide a discoverable, common mechanism for automating the
two and three-quarters parsers that a lot of applications have to
write to handle a config file, CLI, and/or registry values, but why
introduce a syntax for it? A module would do just fine in terms of
function. Are you worried about the look of it, or do you want to make
a change to make it seem more "mainstream"? I don't see the
rationale.
