+1. In addition to it being hard to find keyword arguments for a function, there can be pretty bad consequences for passing in the wrong or misspelled keyword arguments in some cases. For example, when a function has a `kwargs...` slurp and doesn’t use those the `kwargs`, no errors will be thrown for misspelled keyword arguments. Example:

```julia
julia> badfun(;x=1, y=2, kwargs...) = x*y^2
badfun (generic function with 1 method)

julia> badfun(;y=5)
25

julia> badfun(;why=5)
4

```
