Maybe looking at Sigfpe's blog post You Could Have Invented Monads! (And Maybe You Already Have.) will help.
Notice the tense, "could have". I have read You Could Have Invented Monads, and recommended it to students. In fact I _did_ invent monads, in the guise of parser combinators. That is to say, having heard of parser combinators, I developed my own set, which contained operations recognisable with hindsight as the operations of Monad and MonadPlus &c BUT I DID NOT REALISE THAT THAT WAS WHAT I HAD DONE. After reading that blog post, yes.
That's what the "And Maybe You Already Have" part is about.... - -- brandon s. allbery [linux,solaris,freebsd,perl] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxfQQ4ACgkQIn7hlCsL25V5aQCfaweA9PmrInW3BSQwVQdDhdnQ vo0AnRbv58abJ7jINqDsZG2UaXifmRLl =c9Ro -----END PGP SIGNATURE-----
