How to test for equality of types?

[Matthias Walter]

Hi,

how do I test two types for equality? Suppose I have A and B aliasing
some type(s), how do I find out if they are aliases the same thing?

I tried the "is(A == B)" expression, but this does not always work (tell
me if I shall give an example).

On the other hand, according to the spec the IsExpression is not
supposed to compare two aliases with each other.

Best regards,

Matthias
