Backport of #131 to 0.14
Map and Set use some exceptions for control flow that were being raised
with plain
raise
. This meant that stack traces were being created forthese exception that couldn't escape their outer function causing an
unfortunate performance loss. Raising these exceptions with
raise_without_backtrace
avoids the performance problem.Signed-off-by: Geoff Reedy geoff@programmer-monk.net
