I edited my post to properly answer your question.
Use `var` and `var Foo`.
{.experimental: "strictFuncs".}
import tables
type
Foo = ref object
data: Table[string, int]
func readData(f: var Foo, k: string): int =
f.data[k]
if isMainModule:
var f = Foo(data: initTable[string
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
complicated scenario it can catch any errors where I do mutate it by accident.
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
about it.
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
