Maybe my suggestion is outdated, but is it possible to add some
keyword like 'rises' to function/method/procedure declarations?
This way sources will become more self-documenting and much more
predictable. In fact in C++ something like that (although, in a not
very useful manner) already presents and I've always used it when
programmed in C++.
So, by default when 'rises' keyword is not declared in
function declaration, no exception drops are allowed in that function.
Along with that inside such function no other function calls that
drop exceptions are allowed. This functionality of course will
require some major update in user sources and some updates in
RTL sources (only those functions that rise exceptions like
EOutOfMemory), so I think it will be wise to add some command-line
option to disable such behaviour or vise versa.
Please, this is very essential I think.
