What is "."? #60

Closed JeffreyBenjaminBrown closed 7 years ago

JeffreyBenjaminBrown commented 7 years ago

Per wiki/Commands, "." applied to a list is the dequote operator. But I can also apply it to the number 3. If I apply it to a list, it prints the list. If I apply it to 3, it does not show the 3. Does "." mean something else for numbers? Is it defined for other kinds of things too?

It's even weirder! There are four possible expressions you can make out of a 3, a "cheese" and maybe a trailing dot. Three of them evaluate:

45) "cheese" 3 [1] "cheese" 3 46) "cheese" 3. 47) 3 "cheese" [1] 3 "cheese"

The last does not:

48) 3 "cheese". net.fortytwo.ripple.RippleException: argument is not a key/value pair: 3

I looked for words like key and value in Wiki/Commands and didn't find it. Am I overlooking some other introductory document?
