Since many of the arithmetic operators, as well as spaces, require quoting, an alternative form is provided: for any command which begins with a `tt(LPAR()LPAR())', all the characters until a -matching `tt(RPAR()RPAR())' are treated as a quoted expression and +matching `tt(RPAR()RPAR())' are treated as a double-quoted expression and arithmetic expansion performed as for an argument of tt(let).
