Defining binary operators inner product angle brackets

Specific Domains
1

I’d like to define an inner product, and I’m wondering if it’s possible to call it using the angle brackets.

using QuadGK

# "Definition" (quote-unquote)
⟨u, v⟩ = quadgk(x -> u(x)*v(x), 0, 1, rtol = 1e-3)

# Usage
u(x) = x^2
v(x) = x^3
M = ⟨u, v⟩

I’ve seen that there is a list of supported symbols but with the linked file provided it was hard to browse/find the angle brackets.

I haven’t been able to find if anyone has tried/done this before.

It’s currently not possible to do this, because angle brackets are not valid syntax. See also https://github.com/JuliaLang/julia/pull/27712.
