A related issue(which I believe has no topic in this forum yet) is substituting an expression that results in a multiline string into a multiline f-string while matching its indentation.
If a new type of string prefix is made to auto-dedent, maybe the substitutions should match the local indentation.
Some related stackoverflow posts:

I.e. ideally we would have:
```python
def make_g_code():
  nl='\n'
  return d"""\
    def g():
      {nl.join(something(i) for i in range(n))}
      return something_else
    """
```
This still has issues. Newline needs to be put into a variable, for instance. In the case of using this template for languages, great many use braces for delimiting blocks and those need to be escaped inside f-strings.

An implementation that works with spaces only (does not suit my case where mixed indentation is possible) is here:
