(*) Lon ago, Knuth visited UCLA when I was there, and 'structured

structured programs, without gotos, could sometimes make code
/worse/. He shows some code without any gotos that was correct but
extremely difficult to read and understand. Then he showed a
version, with two loops -- one after the other -- and inside each
was a goto into the other. OMG. But this code was clear, concise
and easy to understand.
I recall an old corporate project SE coding guideline: usage of a GOTO
LABEL was allowed if the LABEL is within the reader's page view, i.e.
25 lines (using 25x80 terminal standards).
