You have reused Some_Loop_Name these labels should be unique just like the
compiler output tells you. Having never used the dreaded GOTO I cannot
be certain but I think that this is what the Labels COULD be used for
(if you wanted to die a slow and painful death).

Now a question, why does Ada have GOTOs, why does code need to be changed
to avoid GOTOs problems ? I remember having a bunch of exception handling
blocks within a case statement, I had to create individual names for
each one rather than just using a unified label (eg Exception_Block)
we can overload everything BUT labels.

GOTO has unusual syntax so why not specific GOTO Labels ?

And yes this problem has manifested itself today due to some cutting
and pasting :(
