Top Forums UNIX for Beginners Questions & Answers Are the brains of the UNIXoid working correctly? Post 303031445 by Corona688 on Thursday 28th of February 2019 10:46:42 AM

Code:
T=0 ; for X in {2..100} ; do ((T+=X)) ; done

Loses at code golf, but wins in a world where code must be read, understood, and maintained.

More seriously, Haskell won't replace shell, they've got different jobs. Haskell's real opportunities are perl and python, two omnipresent languages ill-equipped for formal math/logic but often pressed into service with the assistance bolt-on modules. This works but the syntax of calling modules for something you'd expect a builtin to do is inevitably ugly. Something with more orthogonal data structures could do a lot more with a lot less kludge. What can Haskell's data structures do?
