I guess that he considers this a feature for two reasons:

1) He's used to the atrociously poor error recovery of typical C++ compilers. You almost always get different errors after you've fixed the first error.

2) His language's semantics enforce sequential compilation, such that it's not reasonably possible to continue evaluating in the face of many or most errors.

#1 is a consequence of not designing for error recovery from the beginning. He's going to run in to a problem when people want squiggly red underlines in their IDE.

As projects grow in size, #2 is going to breakdown quickly without a good separate compilation unit story.




Come on guys, think about it!

It is trivial to make your test routine log the error but return true so that the compiler doesn't stop.


I'm totally fine with #2, if you do have a good separate compilation unit story. I'm fact, it's how many lisps work, and it works out quite well.

However, I wasn't talking just about your compile time asserts for #1. There's also syntax errors, undefined identifiers, missing or extra arguments, etc, etc. That stuff is hard to get right if you want to report many independent errors. It gets much easier if you can change your language, so don't wait too long to take a swing at it.
