Actually, from less _regular_ languages. E.g. SAS will in some
contexts allow v1-v4 for v1 v2 v3 v4, which is expressive, but of
course it means something completely different in other contexts.
R generally tries to be a regular programming language where things
mean the same wherever they are used, so that expressions can be
picked apart and understood piece by piece. E.g. R doesn't allow you
to specify the tail end of an array using syntax like a[i:end], where
"end" would be equivalent to length(a).
There are irregularities, e.g. the fact that you do help(foo), not
help("foo"), but they tend to get a pain in the long run (How do you
get help on a name contained in a variable? A GUI designer will need a
way to do just that...)
