I'm still familiarizing myself with janet's flycheck bits so likely others are better at reviewing this, but it seems like a nice idea.

Any hints about what ve is supposed to stand for? May be "value" or "variable" entry?

I guess that fc is short for "flycheck".

On a side note, I think the CI thing may be similar to what's described here: janet-lang/spork#258.

I've made a separate PR for that here.

I originally regard it as variable's environment , maybe variable's metadata is more appropriate? I'm so poor at naming...

Yep.

Thanks for the clarification.

FWIW, it seems like there is precedent for entry in boot.janet, e.g.:

• in macex1
• in varfn
• in module/value
• in flycheck-evaluator

Looks pretty good to me, good for one off fixes to make things pass flychecking.
