Topic: Precedence issue

In docs#LinearMap.quotKerEquivRange, I find it a little bit sad to need parentheses around the quotient. Is there a good reason for the quotient notation to have such a low precedence?

It seems odd to me that the precedence of ≃ₗ[
is different to that of ≃[

It seems some of our isomorphisms are :25
, and others :50

I understand that Equiv is data but I think the least surprising behavior would still to have the same precedence as equality.
Patrick Massot (Aug 08 2024 at 13:37):
And I having that giving the quotient symbol a precedence comparable to the division precedence is also the most unsurprising.
