Describe the bug

In Vim9 script, we cannot pass an argument of type any to popup_create().

To Reproduce

Run this shell command:

vim -Nu NONE -S <(cat <<'EOF'
    vim9script
    def Func()
        var what: any = ''
        popup_create(what, {})
    enddef
    defcompile
EOF
)

This error is given:

E1013: Argument 1: type mismatch, expected string but got any

Expected behavior

No error is given.

Environment

  • Vim version: 8.2 Included patches: 1-3151
  • OS: Ubuntu 20.04.2 LTS
  • Terminal: XTerm(353)

Additional context

The {what} argument of popup_create() can be many things; including a number or a string. Thus, it makes sense to use a variable of type any for the first argument of popup_create().

No error is given at the script level:

vim9script
vim9script
var what: any = ''
popup_create(what, {})
echo 'no error'
no error

Which is inconsistent.

If we give a number in compiled code, no error is given:

vim9script
def Func()
    popup_create(123, {})
enddef
defcompile
echo 'no error'
no error

It means that Vim is ok with us giving a number to popup_create(). But that's not what the first error message said:

E1013: Argument 1: type mismatch, expected string but got any
                                  ^-------------^
