I’m trying to create a tree class using Dicts. The base struct is:
```
mutable struct MyNode
name::String
information::Tuple
children::Dict{String, MyNode}
end
```
I have a constructor:
```
MyNode(name::String) = MyNode(name, (), Dict{String, MyNode}())
```
If I try to construct a MyNode from the REPL like so:
```
> tree1 = MyNode("root", (), Dict{String, MyNode}())
```
it works. But if I try to use the constructor I get an error:
```
> tree = MyNode("root")
ERROR: MethodError: Cannot `convert` an object of type Type{Dict{String,MyNode}} to an object of type Dict{String,MyNode}
This may have arisen from a call to the constructor Dict{String,MyNode}(...),
since type constructors fall back to convert methods.
```
What am I doing wrong?

Your code works perfectly here (BTW, thanks for the reproducible test case!). Looking at the error message, I suspect you forgot `()` after `Dict{String, MyNode}` at some point during your testing.

Errr. So quitting the REPL and restarting, and you are correct. It works. I did, in my first iteration, forget the trailing parens. But why didn’t it get loaded over when I reloaded the module file?
