BB abstracts away all the messy bits of event handling. In Delphi, VB,
C# the programmer is responsible for handling each event, e.g. mouse
click, keypress etc. It also means that they are 'bloated' by comparison
with CP which has retained the simplicity urged by Wirth. The price paid
is reflected in the comments about lack of components, lack of
versatility of layout, difficulty in creating freestanding applications.

If it were to be used to create event driven GUI applications a move of
CP to dot NET by incorporation into VS would require that the language
had 'features' added to handle events which would become the
responsibility of the programmer. If people were happy to use CP to
create console applications it would not.

Of course if someone were to take on the job of re-creating a BB
lookalike with all the rough edges smoothed out, all the messy bits of
event handling would be hidden from the user.

But 'it ain't gonna happen' is it? Which is why it seems important to
decide what it is about BB and CP that is really important to each user.
The ease of creating a GUI or the reliability and program correctness
possible with CP?
