I'm pretty sure "reserved words" are conceptually quite different from
variables, yes. Unless you're talking about an extensible language like
LISP or FORTH or Tcl, the reserved words let you do things that you
can't do with functions and variables, and vice versa.
Knowing what's an argument and what's a function is also pretty
important for understanding how a given line of code works. If you can't
look at the code and figure out which function bodies get evaluated, it
makes it really rough to work out what's going on, even in a functional
language.
