Hi Joel,
I think there's a big problem when the docs use a vague term like "convert
to a string," since there are several ways that values may be converted to
strings.
As Andrew Martin noted, the cause of the strange behavior seen by JOIN is
INSERT's behavior (also seen with APPEND).
It seems that INSERT uses FORM to convert values contained in blocks before
inserting them, and TO STRING! to convert values which aren't contained in
blocks. Most of the time the results of TO STRING! and FORM are the same, but
there are several differences.
>> to+form: func[v][print to string! :v print form :v]
>> to+form pi
3.14159265358979
3.14159265358979
>> to+form %file.ext
file.ext
file.ext
>> to+form to binary! "binary"
binary
#{62696E617279}
>> to+form first [abc/def/ghi]
abcdefghi
abc/def/ghi
>> to+form ["abc" "def" "ghi"]
abcdefghi
abc def ghi
These differences correspond exactly to the behavior of INSERT, APPEND and
JOIN:
>> append "" to binary! "binary"
== "binary"
>> append "" reduce [to binary! "binary"]
== "#{62696E617279}"
>> append "" first [abc/def/ghi]
== "abcdefghi"
>> append "" [abc/def/ghi]
== "abc/def/ghi"
>> append "" ["abc" "def" "ghi"]
== "abcdefghi"
>> append "" [["abc" "def" "ghi"]]
== "abc def ghi"
