I like the idea and the syntax, but what happens with the likes of
this...
a: 10
a:: 20
a: 30
Does that produce an 'a in both the global and local context? And if
so, does the third expression above change the local or global value,
or both?
Afterall, we can do this in REBOL...
>> a: 10 b: 20
== 20
>> fun: has [a][a: 50 print a print b]
>> fun print a
50
20
10
Though I doubt it's good practice. (:
