Many (some? Me anyway, but a long time ago:) have been bitten by trying

my $aryref = \qw(A B C);

to generate a ref to an array of quoted scalars, and ended up with a a ref to the last quoted scalar. This is explained in perlref

Taking a reference to an enumerated list is not the same as using square brackets--instead it's the same as creating a list of references!
@list = (\$a, \@b, \%c); @list = \($a, @b, %c); # same thing!

Now, for reasons of my own, I wanted to generate an array of references to scalar, but the twist is that the scalars in question are a list of sequential integers.

Now the easy way to generate a list of sequential integers is the range operator 3 .. 5,

so I tried [ \(3 .. 5)]

and got [[3,4,5]]

Which was not what I expected. It's easy enough to work around

[ map \$_, 3 .. 5 ]

or even a golfish

 [\(@_=(3..5))],

but it seems strange that the first option doesn't do what I thought. Is this a bug, special magic, what everyone else expected?


Examine what is said, not who speaks.

The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.
