Hello all,

Is slash (/) allowed in variable names? I'm reading a tutorial on the
NS2 simulator, and it appears to be using slashes in class names:

set tcp [new Agent/TCP]

I tried to run the following example through tclsh, but as you can see
it didn't work out well:

% set test/blah 5
5
% puts $test/blah
can't read "test": no such variable
.

A. Tcl allows ANYTHING in a variable name. It even
allows nothing (an empty string--'turns out to be
useful occasionally)!
B. However, the rules for $-dereferencing are slightly
different. Try this:

set test/blah 5
puts ${test/blah}
.
