Yes, that clears the compiler error, but it's actually the opposite of what I
want. I want the compiler to see that `f` is immutable, so in a more

I like the strict funcs experimental feature, and I like using it in my side
projects. But I'm having a small issue and wanted to see what others think

Here's the setup: I have a reference type with a private member that is a
table. I want a pure function to be able to read from that
@cblake mentioned it in their post but my personal uses of symbolic algebra
libraries have been for finding analytic partial derivatives of simple but
tedious expressions. Mostly high degree polynomials in multiple variables but
also some other things like 1/x. Also simple arithmetic on polynomi
