Hi Chris,

in principle I agree to your remarks

but I would like to add that I sincerely regret the
absence of standard libraries. But this was already
the case for Modula-2 and it was agggrevated with
Oberon. Althoug the disappearance of easy routines
for reading like ReadLn in favor of Scanners is a big
leap forward it prevents people from switching.

It requires refactoring of the own thoughts ...
something many people have problems with.

regards
