Good to know. I don't think that the documentation is so clear. I, for
example, was tricked by this core doc statement:
Closely related data types are hash! and list!. They are used in much the
same way
as block values, but have special capabilities.
And by the fact that the help of Set speaks of "block" not of "block!":
Sets a word or block of words to specified value(s).
[...]
value -- Value or block of values
If the value is a block, then each of the words in the first block will be
set to the respective values in the second block. If there are not enough
values in the second block, the remaining words will be set to NONE.
It also true that set doc never speaks of hash or list.
But perhaps i've missed some other doc.
Thanks for the info.
