Reverse the words
Problem
A grammar can make a value from the values its parts
made. Parse a phrase — words of word characters separated by single
spaces, with no other punctuation — and produce the phrase with
every word reversed.
Let each word token make its own text
reversed (with flip), and let TOP combine
those into the final phrase. Parse 'hello world' and print
.made.
Example
The program prints:
olleh dlrow
