error handling for local variable used as an inner function parameter

[iwelch]

mutable struct Point; x::Float64; end#struct 

function x()
    Point(x::Int) = Point( Float64(x) )
    isindomain( p::Point )= (!isinf(p.x))

    println(isindomain(Point(2)) && "we are all good")
end

I am going to guess that initializers are not allowed to be local. however, I am neither certain that this is the problem, nor is this a big problem. it can be easily cured by moving the initializer out of the function.

if I am correct, and one should not create function-local initializers, then may I suggest a better error message that says precisely this? the obscure error is just not informative enough, and this can probably be easily detected.

if I am incorrect, oh well, then I am just, as often, confused.

Right; in this example Point is a function-valued local variable of function x. So inside the function, Point only refers to that local variable and no longer refers to the global type name. I agree the error message can be improved though.

At some point this was fixed (v1.0)

ERROR: syntax: local variable Point cannot be used in closure declaration

and then quickly regressed again:

ERROR: UndefVarError: `#5#Point` not defined in `Main`
Suggestion: check for spelling errors or missing imports.

but better than it was originally

ERROR: type DataType has no field contents
