Hi Florian,

While I agree that this is a well thought out transform, I wonder, what
is the motivation exactly? The URI transform allows the computer to
deal with the methods in a straightforward manner, such as in the
NanoSystem metainfo and it's capabilities like:

  String.use :[]=

Also I have an interesting experiment using method_missing to
automatically require nano-methods. Of course I can still do those
things with the above, but I would noless have to run it through your
transform rather then URI's. So there's still a need for a require_esc
and require_nano, etc.

BTW, I wonder, have you enumerated every possibility? Also there are
some odd looking fringe cases like: '__send__!' => '__send___bang'. At
worst though, what if a method is actually called #foo_p? Hmm... now
that I think of it, there is already a method called 'attr_setter'.
I'll give it some more consideration though. In the mean time I added
two new kernel methods #uri and #unuri. So there's another way:

  require uri('nano/array/[]=')

Additionlly I created an exectuable called uri which makes it easy to
look up on the command line:

  > uri '+@'
  > %2B%40

And for reference, here's a chart:

  {
    "!" => "%21"
    "%" => "%25"
    "&" => "%26"
    "*" => "%2A"
    "+" => "%2B"
    "-" => "%2D"
    "/" => "%2F"
    ":" => "%3A"
    "<" => "%3C"
    "=" => "%3D"
    ">" => "%3E"
    "?" => "%3F"
    "@" => "%40"
    "[" => "%5B"
    "]" => "%5D"
    "^" => "%5E"
    "`" => "%60"
    "|" => "%7C"
    "~" => "%7E"
  }
