It’s very strange to be getting back into a language as different to Perl as it is possible to be. I’m fairly conversant with the weird bits of Perl — map, grep, hash usage, objects — but Fortran has a completely different toolkit
That’s not to say it’s a bad toolkit, just very different, F’rinstance, trying to find all the distinct values in an array. In Perl, you just walk through a hash, parallel to the array, incrementing each key for every value found. In Fortran — well, it’s a different story.
