The <…> and «…» constructors break on whitespace.
So <a,b,c,d,e,f> will actually produce the following array:
["a,b,c,d,e,f"]
It's only one item. If we placed space after the comma, that is, <a, b, c, d,
e, f>, you'd get a six item list, but with the commas attached to all but the
final:
["a,", "b,", "c,", "d,", "e,", "f"]
By replacing the commas with spaces, e.g., <a b c d e f>, you allow it to break
into ["a", "b", "c", "d", "e", "f"]
