alpha-dditive??

Kenny Lau (Apr 21 2018 at 23:24):

is that an easter egg

Mario Carneiro (Apr 21 2018 at 23:45):

I tried to PR that almost a year ago and of course it was rejected

Kenny Lau (Apr 21 2018 at 23:45):

lol

Kenny Lau (Apr 21 2018 at 23:45):

what was the reason

Mario Carneiro (Apr 21 2018 at 23:47):

Leo doesn't want to hear about tiny changes

Kevin Buzzard (Apr 21 2018 at 23:48):

that one must be hard to review or something

Patrick Massot (Apr 21 2018 at 23:48):

That one was provocation

Mario Carneiro (Apr 21 2018 at 23:48):

It's not an easter egg, it's a bad find-replace job when we moved from using A B C to α β γ for types

Kevin Buzzard (Apr 21 2018 at 23:48):

it's a pretty spectacular bad find-replace job!

Patrick Massot (Apr 21 2018 at 23:49):

We'll need to be much more careful when we'll to the s/α/G/g in all group theory files

Kevin Buzzard (Apr 21 2018 at 23:49):

Did they change every A to an alpha and then change 100 alpha's back to A's?

Kevin Buzzard (Apr 21 2018 at 23:50):

put it in the pile for the one time patch

Mario Carneiro (Apr 21 2018 at 23:50):

an easter egg would be replacing A with a capital alpha

Patrick Massot (Apr 21 2018 at 23:52):

variables (Α : Type) (A : Type)

Patrick Massot (Apr 21 2018 at 23:52):

Yeah!

Patrick Massot (Apr 21 2018 at 23:52):

Lean doesn't complain

Mario Carneiro (Apr 21 2018 at 23:52):

no, that's shadowing

Mario Carneiro (Apr 21 2018 at 23:52):

but universe shadowing is disallowed for some reason...

Patrick Massot (Apr 21 2018 at 23:53):

No, I the first one wasn't a capital alpha Lean would complain

Mario Carneiro (Apr 21 2018 at 23:54):

I stand corrected

Patrick Massot (Apr 21 2018 at 23:54):

Anyway, I should be sleeping

Patrick Massot (Apr 21 2018 at 23:55):

See you!

Kenny Lau (Apr 21 2018 at 23:58):

I just woke up
