Happy 1st April, everyone!

I think maybe should depend on the mood of the interpreter and thus a random.random() should be added as well to have unpredictable branches

[Bobronium]

LGTM! Maybe.

[ConfirmedPlayer]

Approve

[s3rius]

Suggested change

	RAISE_INDENTATION_ERROR("expected an indented block after 'if' statement on line %d", a->lineno) }
	RAISE_INDENTATION_ERROR("expected an indented block after 'maybe' statement on line %d", a->lineno) }

[Bobronium]

We might want to add more pythonic keywords for old elif and else as well:

I propose:
elif -> ormay
else -> otherwise

maybe answer == 42:
    print("Found the meaning")
ormay answer == 41: 
    print("So close")
otherwise:
    print("Keep searching")

Perfect feature to be added in pytest lib

Nice use of soft keywords.

Please update pattern matching guards to allow the new syntax:

>>> match match:
...     case case maybe maybe:
...          ...

As well as ternary maybe:

>>> maybe maybe maybe else maybe

[GrigoriiKushnir]

Suggested change

	// | "maybe" named_expression ':' block elif_stmt
	// | "maybe" named_expression ':' block elmaybe_stmt

You have no idea how tempted I am to add the release blocker label.

Don't worry I will do it for you 🤣

The steering council will resist!

Btw: You laugh but I am moderately confident the PEG parser can support this atrocity like Atlas holding the world 🌍🙂

This would be the end of Black as we know it. Maybe.

Finally, Python achieves peak performance by just skipping the hard parts. Truly an if you can't solve it, ignore it moment. Guido would be proud. 🐍✨

But honestly, at this point, I don't want Python to handle exceptions. I want it to handle my emotions.

[blaisep]

I believe that functions using maybe handle exceptions better when you wrap them with the decorator @whatsinit_forme

I had to try:

@sobolevn I pushed a commit to this PR. It's not on the PEP ( 😆 ) but @brandtbucher has a way to nerdsnipe me :)

[gvanrossum]

Excellent work!

[sobolevn]

Thanks everyone, I hope we had fun on this 1st April together :)
Now it is time to close this PR :(

[ZeroIntensity]

Long live the BDFL.
