[Xotcl] Abstract class question

[Laurent Duperval]

Hi,

How do you enforce abstract methods? For example:

Class Foo
Foo abstract instproc procdef args

Class Bar -superclass
Bar instproc proc2

Bar barObj

I would like an error to be thrown at the "Bar barObj" line because the Bar
object doesn't define the procdef instproc. Is this rule enforceable? Is my
only way at it to use assertions?

Thanks,

L
