Right now for me it is hard to say whether something is Logo or is not
Logo. I expect that Logo is a fuzzy (cloudy) thing, so there might be
languages (or better say programming environments) which are 50%
Logo-like... or 20% Logo-like.... Most likely if we classify all Logos
we could see some piling-up around the core features of the majority of
Logos... but we could also see some branches/tentacles which bridge a
smooth path from Logo to some other programming languages and
environments. OOP, 3D, multimedia, compilers, networking are all
extensions to the core which bring Logoist and Nonlogoists closer.
For example, a Pascal language + Turtle graphics library and list
processing could be positions somewhere between Logo and Pascal... maybe
closer to Pascal than to Logo, but by all means it will have some Logo
features.
So Logos may form a bell-shaped normal distribution... Or may not?!?
If we have the list of features of two things, then by finding an
appropriate metrics we can calculate the 'distance' between them. Now,
these two things could be two dialects of Logo, or Logo and Lisp, or
Logo and Boxer, or Logo and Pop11. By having the distance we could say
how close are two things.
