Suggestion: Removable blocks #62

Thank you for this amazing library!

One thing I often find myself doing is commenting out debug code, or other non-essentials, before minifying. I'm wondering if it would make sense to add some kind of "remove all of this during minify" blocks, which would be ignored when running the program normally, but deleted by minifier. For example:

x = 10
#minify-remove-start
if debug:
    print(f"Debug: {x=}")
#minify-remove-end
print(x**2)

Thanks again for this amazing work. I'm using it to greatly compress sunfish (https://github.com/thomasahle/sunfish) for the sub 4K chess engine competition :)

Hi @thomasahle, this is a good idea. I think this should hook into the builtin __debug__ constant, e.g.:

x = 10
if __debug__:
    print(f"Debug: {x=}")
print(x**2)

And that whole block would be removed if a --remove-debug option was set.

Version 2.8.0 has been released which includes --remove-debug
