variables

Large part of squeak is implemented using squeak itself. I am curious to know if pseudo variables such as self or true are also implemented using squeak. If the answer is yes, where the implementation located?

Specifically, assume that I want to add new subclass of "Boolean" called "Other" which will represent a third option: neither true nor false. I want that other, the only instance of Other to be similar to the true/false global singletons.

Any ideas? Thank you.

Using free function as pseudo-constructors to exploit template parameter deduction

as seen on Stack Overflow - Search for 'Stack Overflow'
Is it a common pattern/idiom to use free functions as pseudo-constructors to avoid having to explicitly specify template parameters? For example, everyone knows about std::make_pair, which uses its parameters to deduce the pair types: template <class A, class B> std::pair<A, B> make_pair(A… >>> More
