1. Re: we need official libs : Swap
I was silently and strongly supporting the syntax of
{the_junk, the_value} = gets(0)
Until, I saw the following possible implementation.

The only way I know to get around this mess is to either not allow
{valu1, valu2} = function()
OR to set the following rule.
{the_value, the_value} = gets(0) --this equating to.
obj = gets(0)
the_value = obj[1]
the_value = obj[2]
I don't see any problems with the syntax of
{hr, mn, sc, mh, dy, yr} = {cur_hr, cur_mn, cur_sc, cur_mh, cur_dy, cur_yr}
Assume you don't want the {hour, min, sec} but only want the
{month, day, year}. You should still include the first 3 as placeholders.
However, If you only want the {hour, min, sec} and don't want the rest.
You should be able to do the following.
{hour, min, sec} = {cur_hr, cur_mn, cur_sc, cur_mh, cur_dy, cur_yr}
The remaining 3 are simply dropped or ignored.
The more I look at this PERLish code the scarier it gets.
I think I will go hide under the bed now.
