Yes, Tcl allows the use of braces {} as a variable name delimiter. As a matter of fact, if your variable name contains any non-alphanumeric characters (other than an underscore), you will have to use braces around the variable name.

set my-really-cool-name "Pooh Bear"
log "My name is: ${my-really-cool-name}"
However, the use of the hyphen will require the use of braces on all the variable references.
