instanceof Array inconsistencies

[infynyxx]

[1,2] instanceof Array
true

But

a = [1, 2]
a instanceof Array
false

Interesting. This incorrect behavior only occurs in interactive mode for me. The compiled output is correct and so is the result when run as a script. 1.1.0

yeah I forgot to add; it only happens in interactive mode

Yes, the problem is that each statement is getting executed in a new VM instance, so the following occurs:

a = Array
a is Array # false

because it references a different Array each time. Shouldn't be a very difficult fix.

Found the source of the bug: We're looping over the properties in global, but global.propertyIsEnumerable('Array') is false.
