I should probably mention again that legOS supports C++, and supports it
even better if you add void*builtin_new(size_t n){return malloc(n)}; to
the appropriate library, as v0.3.0 will. The rest of this is off-topic.

Interesting. Most compilers aren't - which is very bad for maintenance
if they're written by hand. But then, there are generators for almost
every stage of a compiler now.
I was wondering, did you use generators in writing nqc? What kind of
intermediate representation are you using? Code-generator templates are
probably tricky, considering the bytecodes...
On a different note, we recently made a comparison of several
implementations of standard compiler data structures, e.g., symbol and
definition tables, syntax trees etc. Plain old C came out two times as
fast as standard C++, and over three times as fast as STL code. Of
cause, this only amounts to anything if you're planning on compiling
several thousands of lines of code ;-)
G'Night,
