[Laszlo-dev] defining classes in any order in LZX

[Henry Minsky]

Currently the way the LZX compiler works, this code gives an error
"undefined superclass foo for class bar"

<class name="bar" extends="foo"/>
<class name="foo"/>



because the compiler parses classes internally in the lexical order
they occur in the source, and foo is not defined
yet when it tries to compile bar.

However, we could make the compiler do a pass that stores the class
declarations and parses them on demand
so that the order you declare them lexically doesn't matter.

I guess we've gotten this far without the compiler doing this for you,
but I'm wondering if it would
be a useful thing to do, considering that other object oriented
languages generally seem to allow
it.
