Some old error messages from MPW (which was kind of like XCode for Mac before Mac OS X in one sense).
“String literal too long (I let you have 512 characters, that’s 3 more than ANSI said I should)”
“…And the lord said, `lo, there shall only be case or default labels inside a switch statement’”
“a typedef name was a complete surprise to me at this point in your program”
