Treats \fIlist\fR as a list and returns a decimal string giving
the number of elements in it.
+.SH EXAMPLES
+The result is the number of elements:
+.CS
+% \fBllength\fR {a b c d e}
+5
+% \fBllength\fR {a b c}
+3
+% \fBllength\fR {}
+0
+.CE
+.PP
+Elements are not guaranteed to be exactly words in a dictionary sense
+of course, especially when quoting is used:
+.CS
+% \fBllength\fR {a b {c d} e}
+4
+% \fBllength\fR {a b { } c d e}
+6
+.CE
+.PP
+An empty list is not necessarily an empty string:
+.CS
+% set var { }; puts "[string length $var],[\fBllength\fR $var]"
