There is an optimisation for substitutions of the form
tt(=LPAR()<<<)var(arg)tt(RPAR()), where var(arg) is a single-word argument
to the here-string redirection tt(<<<). This form produces a file name
containing the value of var(arg) after any substitutions have been
performed. This is handled entirely within the current shell. This is
effectively the reverse of the special form tt($LPAR()<)var(arg)tt(RPAR())
which treats var(arg) as a file name and replaces it with the file's
contents.
