Any chance of changing assignment in conditional from error to warning?

[rslepon]

Godot version:
Godot_v3.1.1-stable_win64

Issue description:
At the moment, gdscript does not allow assignment in conditionals, such as "if a = b:", yielding an "Unexpected assign" error.

While I understand the wisdom of this, I can also see some scenarios where allowing these would make code more readable and maintainable, which is no less important. Here is one example, for parsing a string that may have a host of different formats:

if regexmatch = regex1.search(string):
   [extract some data from groups collected in regexmatch]
elif regexmatch = regex2.search(string):
   [extract some data from groups collected in regexmatch]
elif regexmatch = regex3.search(string):
   [extract some data from groups collected in regexmatch]
elif regexmatch = regex4.search(string):
   [extract some data from groups collected in regexmatch]

So, any chance of changing assignment in conditional from error to warning?

Oooh, this reminds me of #7222

I was going to revive it after the warnings were added. There's no reason to reject it now 😏

Duplicate of #7222 and proposals have their own tracker now.
