Calling changing the syntax on unsuspecting users _editing_code_ is really a stretch of gargantuan proportions. And I don't really care whether it's the compiler, the linker, or mega_mojo-2.546-alfa5-preview18, what ever it is, it runs on a computer so that whatever is being done would be fast, automated, and therefore efficient. If the programmer knew what to do with the input, the computer should churn through it, instead of chastizing the user and making them pay for the authors' oversight.
Otherwise, a computer makes no more sense than a toy does.
If I want to use a computer as a toy, I'll go play a video game. The rest of the time, it's a tool, a tool to do something an order of magnitude faster than a human could. If it slows me down because it requires me to babysit it, I have a problem.
