[BUG] Vararg does not work on recent Julia versions #261
Description
Describe the bug
A CLI function of the form:
@main foo(xs::Vararg{String}) = foreach(println, xs)Errors with ERROR: LoadError: TypeError: in <:, expected Type, got Vararg{String}. See the full stacktrace at the bottom of this post.
Version of the package:
- Julia 1.10-beta3
- Comonicon 1.0.6
This does not happen on earlier Julia versions
To Reproduce
Execute the following script
using Comonicon
@main foo(xs::Vararg{String}) = foreach(println, xs)This presumably happens because Vararg{String} isa Type returns false on Julia 1.7 and later.
Full stack trace:
ERROR: LoadError: TypeError: in <:, expected Type, got Vararg{String}
