In that case, you should be looking into how to make it a pragmata,
rather then pushing the idea on perl6-language. It shouldn't be too
hard -- a matter of using the equivalent of perl5's
UNIVERSAL::AUTOLOAD,
and the OUTER:: scope.

The fact that this keeps recurring on P6L is pretty indicative, I
think, that a lot of people don´t value the ability to have an array,
hash, and scalar of the same name quite so much as they regret the need
to respecify the types of all variables every time they´re used.
If it´s really that simple to do, then I´m willing to bet it´ll be
used early and often. Making it a part of ´core´ and in fact planning
to migrate perl in the direction of less useless line noise DOES seem
to me to be a valid task for -language.

I believe that people should be given the choice as to whether to use $,
@, or %, or not.My suggestion was one possible way to achieve making $,
@, and % optional, while still allowing their use and not changing the
existing perl 6 language. This is could be done by simply allowing hashs
and arrays to be defined in the function namespace. The existing
seperate array and hash namespaces would also be retatianed with their %
and @ usage as well, giving people choice. I want very much to preserve
peoples choice as to which way to do things and I do not want this
suggestion implemented in a way if it takes away peoples right to use $,
@ and %, or impacts Perl 6's existing grammer in other ways.
One of the reasons I suggest this idea, is indeed variables are very
commonly used in many cases, in a program, and typing the prefix
characters in my expierience at times is a bit of annoyance, especially
since it requires a trip to the shift key. This is not a big problem
with things that are seldom used in a language, but when it applies to
something as commonly used as variables, it becomes more significant.
Maybe its not a huge thing but it is a bit of annoyance at times to me.
It may not be to other people thats why if people want to keep using $,
@, And %, they should be able to, and I will still want to use them
myself at times.
I strongly believe in TIMTOWTDI (There is more than one way to do it),
which is one reason I like Perl, is that it gives people freedom, does
not restrict them, and gives them flexibility and as many choices as
possible to how to best accomplish something. I certianly hope Perl 6
can continue, and even expand this.
