Hey, wait a second. How do you throw without allocating?
I think exceptions should be ok. You optimize the typical path,
and exceptions are (by definition) an exceptional path. If they
are also unacceptable, you could restrict yourself to nothrow
functions. (Which can still throw Errors... but meh they are
even *more* exceptional)
Hardly so. Any exception allocation can trigger GC collection
cycle and Phobos does not provide any other way to handle data
errors. Any application that operates on some external user input
will be subject to DoS attack vector if it uses Phobos directly.
It was huge performance killer for vibe.d last time I have
checked, for example.
