probably not - unless you wanted to introduce ';'s to ruby too:


cfp:~ > cat a.rb
x = 1

result =
x / 4 * 2 /
42
p result

def x(*re) 'forty-two' end

result =
x / 4 * 2 /
42
p result

result =
x(/ 4 * 2 /)
42
p result


cfp:~ > ruby a.rb
0
0
"forty-two"

Dang that does seem ambiguous then. Ahh well.

My latest wish is that
unexpected $end, expecting kEND

would say something less cryptic--like "unexpected $end (end of file)
expected word "end" "

Assuming you mean Range#to_a (i.e. an instance rather that class
method) I don't think it's becoming obsolete.

There was talk some time ago when Matz changed 1.9 to use to_splat
instead of to_a that ranges wouldn't be splatted, e.g.

a = *(1..3)

In 1.8 this sets a to [1,2,3] whereas at one time in 1.9 it was to
have set it to [(1..3)].

But testing with a fairly recent irb1.9 this seems to be one of the
changes which has been backed out of 1.9.

It throws warnings as deprecated, for some reason. I like it!

And my latest wish
variables that can end in ?
Oh wishing star...
Take care all!

I don't think so:

shadowfax:~/Documents/terralien/dltsolutions/enrollnow rick$ ruby1.9 -v
ruby 1.9.0 (2007-10-25 patchlevel 0) [i686-darwin8.10.2]

-we '(1..3).to_a'
shadowfax:~/Documents/terralien/dltsolutions/enrollnow rick$ ruby1.9
-we 'p (1..3).to_a'
-e:1: warning: (...) interpreted as grouped expression
[1, 2, 3]
shadowfax:~/Documents/terralien/dltsolutions/enrollnow rick$ ruby1.9
-we 'p((1..3).to_a)'
[1, 2, 3]

"unless you wanted to introduce ';'s to ruby too:"

Hopefully a mandatory ; on the end of each line, as is the case with
perl,
will NEVER appear in Ruby ... but then again who would wish for bad
stuff ;-)


"variables that can end in ?"

I dont like this, mostly because we can use method calls such as
dragon.hungry?

And I would not want to have a variable inside the dragon that
has something like ... i dont know

hungry? = true

I'd rather have a variable that would state
is_hungry = true

instead and then query if the dragon is hungry by using either
is_hungry? or hungry?

(By the way, an accessor_read that can query variables with ? on the end
would
be nice in std ruby too... I am not complaining at all, ruby is so
flexible,
I already use this for my code and i love it, like @file.readable? that
queries a "special" reader accessor... i think it reads nicer than
@file.readable but this is just my opinion)


But I know what i would like to REALLY have:

* real keyword arguments in 2.0

Not sure what those are.

My latest wish, oh wishing star...

(I think something in osx does this)

begin_funcion_name param1 keep_going_function_name param2 end

# so you can have your function calls read really like English

run_if_queue_below 24 every 24 seconds

yeah
Stay well.
