Comment (by mkoeppe):
The code in `add_to_integer_space_dimensions` matches the last example in
the documentation that you cited. I'm assuming it's correct. Besides, it
was copy-paste from elsewhere in ppl.pyx.
{{{
Alternatively, you can use try/finally which will also catch exceptions
raised by subroutines inside the try:
def try_finally_example():
sig_on()
try:
# (some long computation, potentially raising exceptions)
finally:
sig_off()
return something
}}}
