Message: [QUOTE="Peter Keller, post: 4872007"] That's not entirely true. Example: # BEGIN CODE #! /usr/bin/perl $foo = 12; $foo{'key'} = 34; $foo[9] = 55; print "$foo $foo{'key'} $foo[9]\n"; exit 0; # END CODE C has similar problems between type names and functions: /* Begin Code */ #include <stdio.h> #include <stdlib.h> struct XXX { int foo; }; void XXX(void) { printf("Hello world\n"); } int main(void) { struct XXX fg; XXX(); return 0; } /* End Code */ Nearly all languages have different namespaces for their semantic ideas: functions, types, variables, etc, etc, etc. Symbols often intersect in representation: the symbol 'foo' in one namespace is identical to the symbol 'foo' in another namespace. They rarely, but sometimes do depending on the language, intersect in meaning. An example is calling a higher order function in scheme versus lisp. In scheme you simply call it, in lisp, you use funcall. Later, -pete [/QUOTE]
