# % set string(1 "a string"
# % string length $string(1
#
# Giving this command in tclsh will not work, the command will not
# finish. But
#
# % string length ${string(1}

set knows its second argument is the variable name, and so it figures out some
way to parse it. $ knows that a variable name can follow, and tries to find the
longest prefix that is valid variable. ${...} again knows the entire extent
of the variable name and figures out a way to parse it.
