Shouldn't list.pick be list.rand? Or, list.rand should be a synonym for
.pick(1). Heck, I'd like hash.pick or rand too.
I love list.int. Love. I've added that (aka .round, .floor, etc.) and
some variation of rand and pick to just about every TT thing I've done.
Of course, now someone will want ".cast". :)
If not in TT2, then TT3 for this one.

I've included a patch that adds several vmethods that are currently in
CGI::Ex::Template that I have found very, very useful. I've included the pod
for the new methods in the body of this email for discussion. The patch
includes code, pod, and tests for each of the new methods.

New Text VMethods
=item '0'
Essentially the same thing as the item vmethod. Allows for items
to truly behave like lists - without having to call the list
vmethod.
[% thing = 'foo' %][% thing.0 %]
=item int
Return the integer portion of the value (0 if none).
[% thing.int %]
=item fmt
Returns a string formatted with the passed pattern. Default pattern is %s.
Similar to the Perl6 fmt method for scalars. Also similar to the format
filter,
but doesn't split the string on newlines like format does.
[% thing.fmt('%d') %]
[% thing.fmt('%6s') %]
[% thing.fmt('%*s', 6) %]
=item rand
Returns a random number greater or equal to 0 but less than the
item itself.
[% thing = 10; thing.rand %]
New Hash VMethods
=item fmt
Passed a pattern and an string to join on. Returns a string of the
key/value pairs
of the hash formatted with the passed pattern and joined with the passed
string.
Default pattern is "%s\t%s" and the default join string is a newline.
Similar to the Perl6 fmt method for hashes.
[% myhash.fmt('%s => %s', "\n") %]
[% myhash.fmt('%4s => %5s', "\n") %]
[% myhash.fmt('%*s => %*s', "\n", 4, 5) %]
New List VMethods
=item fmt
Passed a pattern and an string to join on. Returns a string of the values
of the list
formatted with the passed pattern and joined with the passed string.
Default pattern is %s and the default join string is a space.
Similar to the Perl6 fmt method for arrays.
[% mylist.fmt('%s', ', ') %]
[% mylist.fmt('%6s', ', ') %]
[% mylist.fmt('%*s', ', ', 6) %]
=item pick
Returns a random item from the list. If a numeric value is
passed and is greater than one, then a list of random
values from the array is returned (Note: the same value
may be returned multiple times as each pick is random).
[% mylist = ['a' .. 'z'] %]
[% mylist.pick %]
[% mylist.pick(8).join('') %]
