repeat with me:
const very ugly;
private protected friend template, ugly;
pass by references for one function or operator good;
references like alias ugly;
pointers good;
classes good;
constructor/distrctor very good;
malloc/free good;
C++ library seems ugly;
C library seems ugly;
C and C++ (operator, overloading too) languages very good;
assembly languge [or base language] very good;

I used to program "somewhere between" C and C++, starting with Microsoft
development products. I think it was MVC++ 4.

One thing I liked about the Gemisch was that I could calculate a value
with C syntax, and just cout<< once I found it. The conversion
specifiers for printf are a huge pain in the ass until you stack up
enough references that you've got a decent chance of getting it right.

I think I ended up on the C side because of the pull from unix.

Well, you only need to stack up one (good) reference.

As in "Oh I do like to be beside the C side"? I knew Unix was
attractive, but I didn't realise it was tidal.

Lenore will be pleased.

So who is Lenore anyway? There will be a test later on.
