Working with items of the same name, from different locations (units,
namespaces), requires qualifications all over. That waste of characters in
source code makes code less readable to me.
Waste of characters? Not really. Write xyz.TFoo is not so different of
TxyzFoo. There is one char more.
How I will know all prefixes of all libs in the internet? If I choose
the prefix "rx", I will have conflicts with RXlib, for example.
Graeme chose the same prefix the Lazarus did in some classes:
TfpgXXXX ("fpg")
The prefix is not needed. It makes it easier, but is by no means a
requirement, as long as you keep the unit names separate.
Compare
Edit1 : myedit.tedit
to
Edit1 : tmyedit
In the second case, you'll cover 99% of all cases.
If by any chance there is an overlap, then the first scenario
edit1 : myedit.tmmyedit
is still an option.
I work 12 years with lots of libraries, and I have exactly once (1 !)
encountered a problem with duplicate names; when Delphi introduced strutils,
it clashed with rxlib's strutils, which was subsequently renamed to rxstrutils.
problem solved.
So namespaces: yes, nice to have.
But do they solve an urgent problem ? I don't think so.
