Take note of how the command syntax appears in the man page:
http://tcl.tk/man/tcl8.5/TclCmd/regexp.htm

regexp ?switches? exp string ?matchVar? ?subMatchVar subMatchVar ...?

Note there's no quotes or braces around 'exp' -- it can be a string, a
variable reference, the result of a command, anything that is a single
word.
