I just would like to know why it is allowed to build classes with
abstract
methods. AFIK it is different from other compilers and it is a
bit strange
for
me.
Delphi gives exactly the same warning.
I don't remember that.

Yes I trust you don't wory, just my mind is playing with me :)
It is allowed to create such instances: as long as you don't call
any of the
abstract methods, there will be no problem.
Is there a way to abort the compilation in this cases instead of a
warning ?
Currently not.
Thanks
