[Jprogramming] Joining lists

[Raul Miller]

If I define:
   a=:?~1000000
   b=:0.1+?~1000000
   c=:?~1000000

I get:
   timespacex 'a,b,c'
0.016585 6.71104e7
   timespacex '>a;b;c'
0.012863 5.0334e7
   timespacex '>a;b;c'
0.011867 5.0334e7
   timespacex 'a,b,c'
0.015703 6.71104e7

So it looks like >a;b;c is slightly more efficient than a,b,c, but
it's nowhere close to a factor of 2, so I think I'd ignore this issue
in most contexts.
