Revise fails on nightly? #593
Description
As of updating to last night's nightly from 2020 Dec 10's build (I skipped all the builds in between), Revise fails (on multiple, seemingly unrelated files; all files that I've tried). I have been updating packages in the meantime, but it's plausible I haven't updated in two weeks, so it could've been a Revise update. I get one of two errors:
┌ Error: Failed to revise /home/graham/git/NeuralModels/src/nonlinearity.jl
│ exception =
│ TypeError: in <:, expected Type, got Vararg
│ Stacktrace:
│ [1] top-level scope

│ Revise evaluation error at /home/graham/git/NeuralModels/src/nonlinearity.jl:7

or
┌ Error: Failed to revise /home/graham/.julia/dev/AxisIndices/src/abstractarray.jl
│ exception =

└ @ Revise ~/.julia/packages/Revise/34vmN/src/packagedef.jl:699
It's maybe worth noting that both of these errors were in response to my putting an @show x line inside a function, or removing said line (the code loads and runs fine in either case with a REPL restart)
Since all this happens in the background, I'm not really sure how to debug this, but I'll try to create a MWE with a dummy package or something and then see if I can't narrow down what update triggered this (though I won't be able to test julia builds between Dec 10 and Jan 8 since I didn't download them -- but I can at least say whether or not the current Revise version works on the Dec 10 build)
