Pairs of identifiers
Frequently functions appear in pairs like
show and so on.
Libraries are a lot easier to use if they use a consistent scheme of names for related functions.
It is even better if many libraries would share the same scheme.
This can be useful both for designing function names and
for easy guessing of the counterpart of some function.
Here is a collection of some pairs of identifiers I stumbled on in AmigaOS, MUI, Modula-3, Haskell libraries, and C++ STL. This could be a basis for further discussion.
It would be great if the discussion lead to a more streamlined collection where for instance some duplicates are removed.
