The string pointed to by char* is prefixed with an integer. It's no separate variable; it, in fact, is not referred to by any variable. Much less a private one.

STL mandates that even linked list have O(1) size functions. And as for function call overhead, it's called inlining

Trust your compiler's optimizations, or get staked and use assembly

Like that loop tip. If you're using a tracing JIT, loops are what they feed on. If you're using C, they've already thought about it. Also note code cache might make a loop faster than an unrolled one

As for Josh's talk of std::string, ignore him. Spec doesn't define implementation, hence

D and C# allow for both integers and strings to be used in switch statements, relying on the compiler to choose a suitable form of jump table (Probably hash jump table, as in the case of sparse integers). Functional languages have pattern matching to cover the syntactic terseness of a switch, and due to an abundance in the semantic qualitiy of referential transparency, optimizations can be applied to output assembly resembling a switch

#3, why are you explaining types? The only languages I've come across that lack multiple primitive types are esoteric languages, and I don't think any of these suggestions would really suit Thue

I disagree with delta timing. You suggest a naive approach which can cause wall jumping in extreme cases. Just program efficiently in the first place, and all is well

Pseudocode is a joke. If I want simple syntax and clear semantics, I'll use Python. If you want to do the whole writing out algorithms without dealing with language hassles, draw out some graphs. Pseudocode doesn't offer enough useful abstraction to call for leaving away testing at a click of a button

#8 is a whole lot of nothing about something
