Of course. But most languages derived from C have a single lexer token
"whitespace". That one token is significant, but these are all the
same:

foo bar
foo               bar
foo
bar
foo/* this one wasn't originally the same*/bar

Python handles differently source files that differ only in
whitespace. It's not only indentation; newlines are whitespace too,
and they're significant. In C-derived languages, it's only
presence-or-absence.
