Add error hint for `setindex(::Type, ...) about julia HOT 4 CLOSED

It could likely be added as an additional MethodError hint with register_error_hint (or it could be a method definition like setindex!(T::Type, val, inds...) = error("Cannot assign a value to $T directly. Use $T() ...") instead, but the former seems probably preferable?)

from julia.

Would something like this work? - ERROR: Cannot assign value to 'Dict' type directly. Use 'Dict()' to create an instance before assignment.

from julia.

looks great! (although obviously this shouldn't be specifically for Dict but whatever the type name happens to be)

from julia.

Thanks! How far should it go? ERROR: Cannot assign value to '<TypeName>' directly. Initialize with '<TypeName>()' before assignment. seems generic enough. Also: Where in the source code is this error actually being triggered? I assume It's multiple methods forming the final string, but where would I usually start at?

Cheers
