Java 2 didn't have streams nor iterator combinatorics, not sure what you mean?
How would you have preferred to solve it? Using for loops?
Python style iterator comprehension
(wonder if someone has made that into a macro. if no one has I will)
I don't think it would be readable. Too much going on. You'd need an outer iter over lines, an inner over words, a check for number and a conversion. And there would be zero error handling.
No less readable than half the Python comprehensions I've written.
Not necessarily. The macro could look for a ? at the end of the final expression (the bit that comes first in a comprehension) and return a Result.
Right, of course, I meant no error handling in the Python impl
