Today around 1:41pm, Tom Christiansen hammered out this masterpiece:

Goodness man, I got it, I have gotten it. Perhaps I'm using wrong terminology,
but I understand.

Well, there is a mention to the effect of:
@uniq = keys %{{%foo,%baz}};
in perlfaq4.
And perlfunc says that keys only works on 'named hashes'. I suppose to a
seasoned veteran, that's sufficient.
There is no documentation that states:
``keys() just doesn't work on lists and/or arrays, you must use this syntax to
force that to work:
@array = keys %{{@array}};
''
Or something like that.
This suggestion was brought up as a means to make these functions more user
friendly.
If it's impossible, then I'll be glad to forget about it.
[Insert many replies that agree here, I'm sure.]
