Binary size: push_constant_text -> push_text when not time-critical. Especially in error handling, and code that does a lot of other string operations anyway the speed gain is not wort the 100+ bytes code size of each instance of push_constant_text This saves about 20K of code size (main pike binary), while not really changing the speed much. push_constant_text that seemed to be in at least pseudo-time-critical code was kept as they were. On a related note, push_constant_text(":") four times in a row creates four different string variables, for obvious reasons. Some of the remaining push_constant_text really should have a module/file local string variable, even though that is more bothersome to create. It might be nice to have this in .cmod files automatically.
