I have a custom type with a constructor function, and I have another type
that has several members of this type. The problem is that the inner type's
constructor doesn't get called when I would expect it to. Here is a minimal
example to show what I mean:
type MyType
member::Int64
anothermember::Float64
end
function MyType(value::Int64)
return MyType(value, 0.0)
end
foo = MyType(42) # ok
type MyOtherType
member::MyType
end
bar = MyOtherType(42) # this gives an error
The error this gives is as follows:
ERROR: `convert` has no method matching convert(::Type{MyType}, ::Int64)
in convert at base.jl:13

What can I do to make this work. E.g. how can I ensure that `convert` will
call my type's constructor appropriately? (The `convert` documentation
doesn't say.) Or is there a better way to do this?
