Describe alternatives you've considered

The following code is some complicated.

import { env_var_get } from "std/env"
const home = trust env_var_get("HOME")
import { history } from "{home}/.amber/helper/git.ab"

What is the issue? that the code is not compiling in bash with the possibility to use ~/?
If you can share also the bash generated and better details so we can investigate, because it is a bug if the variables are not expanded automatically.

Invoke amber run demo.ab, and stack trace as following:

 ERROR  Could not read file '~/IdeaProjects/amber-demo/helper.ab'
at demo.ab:5:21

5| import { sum } from "~/IdeaProjects/amber-demo/helper.ab"
6|
No such file or directory (os error 2)

Replace ~ with $HOME value when reading module path
