what if we had special support for python -c (and maybe in some other places
like exec(), but definitely not for source files) for the purpose of
one-liners? Then the syntax wouldn't need to be suitable for general purpose
use, and you could do something like "have ~{ ~} ~; as alternate spellings of
INDENT, DEDENT, and NEWLINE respectively"
python -c 'import os~;for key, value in os.environ.items():~{if
key.startswith("XDG"):~{print(f"{key}:{value}")~}~}'
