Dear Brad,
Thank you so much for taking the time to reply!
I wrote a few notes inline, below:

Oh, thanks, now it makes sense.

This comes from the length of the array; the array is coerced into a numeric
I'd like to help with my 2 cents.
Given your comparison with R, sum, and mean are expected to play with a
vector rather than log and sin are expected to play with single numbers.
Then, the expected behavior for numerics types in Raku still the same as in
R. The difference is only that the

Here's another way of phrasing these answers-
Some routines like "join" operate on strings, and thus coerce their
argument to a string.
Some routines like "sin" operate on numbers, and thus coerce their argument
to a number.
Each class defines how it coerces to Str or Num, regardless of what is

Thank you Timo for the favor of a reply!

Thank you, Joe, for taking the time to write such a cogent reply. And
thanks to Tobias and everyone else who has taken the time to reply to my
questions.

but they don't have to, since Aureliano started with "wrap" they can be
actual wrappers:
sub map-over-arg(\A) {my =nextcallee; A.map:{nextone $_}}

I did not find anything that explicitly requires @array.split() to force
@array into a string, but there are tests in
Functions in Raku tend to have one job and one job only.
`split` splits a string.
So if you call `split` on something that is not a string it gets turned
into one if it can.
This happens for most functions.
Having `split` be the only function that auto-vectorizes against an array
would be very

I think were the present topic has to do more with the
strong/weak/gradual typing debates-- here Raku is doing an
automatic type conversion that a "strong-typing" fanatic
would sneer at.

So I guess the first question I have is whether the 'auto-joining' of array
elements is specc'ed or not.
What you seem to be saying is that when calling a function on an array, the
first response is for Raku to call something similar to 'cat' on the array,
then proceed to process the function
