Comment on What could go wrong trying to solve AoC in Rust?

  Python style iterator comprehension

  (wonder if someone has made that into a macro)

    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.

      zero error handling.

      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
