The website still points to the doc from the older repo
This repo contains a doc with several useful updates but the website shows an older document with some mistakes. Please republish the latest refresher. (Thanks for this resource BTW).
Misleading expression in Methods, Blocks, and Procs
Hi
I think this is misleading
say_these_things(thing2="ha")
it implies that you are explicitly specifying the thing2 variable and leaving thing1 as it's default but in fact, you are simply passing a value for thing1 which is the return value for the expression thing2="ha".. which is "ha"..
2.1.0 :069 > say_these_things(thing2="ha")
ha
blah
=> nil
I'm not even sure if it is possible to explicitly specify a named variable when calling a method.. if it is not possible, perhaps might be better to leave this bit out entirely
