VSCode terminal, 1.12.0-rc3, MethodError: no method matching iterate(::Nothing) #673
Description
Not sure if it's Cthulhu, or the vscode-julia extension, but in the VSCode integrated terminal on Windows, I cannot descend into many functions.
I have my depot on a different drive, if it matters, and Cthulhu is up-to-date.
This doesn't throw an error on the Windows terminal.
Looks a little like #148, but not really, I guess.
