Maybe he one and true answer for all of the above would be to have:
try vs try
try except
try finally
except except
end; end;
finally
end;
except
end;
so with except being optionally allowed either side of 'finally' ?
I haven't actually tried this, but what would this do?
try
try
except
end;
finally
try
except
end;
end;
If this is what is really desired, is this a good construct?
try
...
except
...
finally
...
except
...
end;
The idea for the construct is to replace (if I take your last example)
the following construct:
=== example begin ===
try
try
try
except
end;
finally
end;
except
end;
=== example end ===
The variant
=== example begin ===
try
finally
except
end;
=== example end ===
would replace
=== example begin ===
try
try
finally
end;
except
end;
=== example end ===
and
=== example begin ===
try
except
finally
end;
=== example end ===
would replace
=== example begin ===
try
try
except
end;
finally
end;
=== example end ===
These are the most common usages of nested try...finally/except blocks
and thus can increase the readability. Thus no change in semantics, only
in "formatting".
