Don't use double quotes then :-) Inside double quotes all of command
substitution, variable substitution, and backslash substitution are
performed. In a regexp you typically want none of this. You usually do
want the whitespace to be significant, so it is good to quote it in
braces though (unless you like quoting all your whitespace).

See <https://www.tcl.tk/man/tcl8.6.13/TclCmd/Tcl.html> for a very short
page that has *all* Tcl syntax!
