vsh: Cannot use `os` constants without importing `os`

[csfore]

Describe the bug

In a .vsh file, the module os is currently imported with all of the functions being global so you don't need to import it. Using constants from the module, however, does not work without having to import os.

Expected Behavior

I expected println(args) to print the arguments provided

Current Behavior

println(args) currently errors with

test.vsh:1:9: error: undefined ident: `args`
    1 | println(args)
      |         ~~~~

Reproduction Steps

In a .vsh file (or extension-less)

println(args)

Possible Solution

? println(os.args)?

I am not sure if .vsh files should allow the implicit import of os module variables/constants.

? println(os.args)?

This doesn't work.

println(os.args)

test.vsh:1:9: error: undefined ident: `os`
    1 | println(os.args)
      |         ~~

I am not sure if .vsh files should allow the implicit import of os module variables/constants.

Agreed, as it could have unintended consequences, but it should still warn the user that constants are not implicitly imported. (suggesting importing os, maybe?)
