[fpc-devel] is that intended? private type section in classes versus visibility

Renaming existing units for one project that conflicts is not a
solution/option either.

Does FPC support dotted unit names? eg
  freepascal.rtl.classes.pas
  freepascal.fcl.simpleipc.pas
  freepascal.fcl.fgl.pas

then fpGUI and LCL (and any other projects) could do similar.... eg:

  fpgui.button.pas
  lcl.buttons.pas

Currently fpGUI already does something similar (as I stated before) by
prefixing all classes with 'Tfpg' and all units names are prefixed
with 'fpg_' eg:

  fpg_button.pas
  fpg_grid.pas

I did this to minimize any possible conflicts, but other projects have
not done this, so they stand a much greater chance to get conflicts
with FPC or other projects.

I guess Object Pascal users will feel this is "weird" at first - I did
too with my change in fpGUI, but you soon get used to it. The benefits
outweigh with temporary "weird" factor. I would probably have
preferred a "dotted" unit naming format, but I think last time I
tried, FPC didn't support a dotted unit name.

Why not something like IInterface or IUnknown does by using a GUID
somewhere in the unit.
But then comes the problem that not all editors can generate a GUID
via a keyboard shortcut - but then, how to they program with
Interfaces (so maybe a GUID is not a issue).
