Sergei Lebedev 87d1f6ba08 error_already_set::what() is now constructed lazily ... Prior to this commit throwing error_already_set was expensive due to the eager construction of the error string (which required traversing the Python stack). See #1853 for more context and an alternative take on the issue. Note that error_already_set no longer inherits from std::runtime_error because the latter has no default constructor.		2019-08-28 10:36:19 +01:00
