[Jprogramming] Unbox request for requests

[Raul Miller]

As you point out, this works:
   + - (1 : '`u') `:6
+ -

If we fully parenthesize that expression, it looks like this:
   require 'trace'
   paren '+ - (1 : ''`u'') `:6'
((+ (- (1  : '`u'))) `: 6)

So when you put parenthesis around (1 : '`u') `:6 you break the expression.

And, as an aside, your original expression did not actually need any
parenthesis:
   + - 1 : '`u' `:6
+ -

Thanks,

However, this is so useful and prevalent in J that I think its a good fit and will help to modernize and grow the language. Can you provide some details on how you think built in support should work?

I have begun working on a re-implementation of gerunds that should fix some bugs and allow some new features. This is working out to be a somewhat long term project and I'd like to keep things fresh and exciting in the meantime.
