And in terms of the complex types I can see the use case definitely. In
terms of the REPL and the changes in this PR, a `%define` does the same as when
GLOBAL_CONFIG gets created with a `-z` for complex types. In either case, the
complex type gets loaded as a string.
For example, I launched Full Dev and created a GLOBAL_CONFIG that
looks-like this.
```
{
...
"foo": "{'bar' : 'blah'}"
}
```
I then launched the REPL in a debug session with a -z. The value for the
key "foo" is a string.
