Here is a minimal example:

```julia
f(x::Int; y::Int = 1) = x + y
f(1; 2)

```

This produces an error:

which is not very informative. It doesn’t tell you line numbers, and from “BoundsError” I had a hard time figuring out that I was passing a keyword argument wrong.

Should I raise an issue to improve this error message?

Good to know it’s being tracked. Thanks.
