Personally, I don't know why Brenda Baker isn't famous.
People found the converted code to be easier to
understand--even
when they had written the original code themselves.
I ran it on a number of Fortran programs in the EE department
at the U of MD. When it *didn't* resolve loops into Ratfor
style WHILE constructs and the like, it usually meant there was
a bug. I found at least two or three bugs this way.
