In Python the [try …
except](https://docs.python.org/3/tutorial/errors.html#handling-exceptions)
statement has an optional `else` clause. It is useful for code that should only
be executed if the try clause does not raise an exception.
In Nim (like in C++) we have to write:
try:
# Line which might raise an exception.
# Potentially lots of
# other lines which
# should only be
# executed if no
# exception was raised.
except:
discard
Run
with `else` this would read:
try:
# Line which might raise an exception.
except:
discard
else:
# Potentially lots of
# other lines which
# should only be
# executed if no
# exception was raised.
Run
The use of the `else` clause is better than adding additional code to the `try`
clause because it avoids accidentally catching an exception that wasn't raised
by the code being protected by the `try … except` statement.
IMO it also makes it clearer in what code an exception is expected to happen.
Do you think an optional `else` clause would be worth adding to Nim?
