Aliasing fun

[Robert Dewar]

<<But we are of course, not talking in a formal setting here, nor have i
applied a formal meaning of undecidability (except in a few cases when
referring to papers), though i am quite aware of
what it is.

Undecidability IS a formal term, with a formal meaning, if you have been
using the term in any other sense, then no wonder no one has been able
to understand what you were saying.
