\ define " (double-quote) as an alias for s", and make it a prefix

: " postpone s" ; immediate

\ make .( a prefix (we just create an alias for it in the prefixes list)

: .( postpone .( ; immediate

\ make \ a prefix, and add // (same thing) as a prefix too

: \ postpone \ ; immediate

: // postpone \ ; immediate

\ ** add 0b, 0o, 0d, and 0x as prefixes

\ ** these temporarily shift the base to 2, 8, 10, and 16 respectively

\ ** and consume the next number in the input stream, pushing/compiling

\ ** as normal
