Odd error with taking more elements in list

[refi64]

Just try:

2#""

It gives:

Cannot read property 't' of undefined

Looks like the oK bug is simply for the case where you're trying to "take" from an empty list. Should be a straightforward fix.

The official K5 interpreter produces a few surprising results, mainly the behavior for 3#"":

 3#""
"   "
 3#()
("";"";"")
 3#0N
0N 0N 0N

I believe it goes like this (in a Python-like pseudocode):

a (#) b =
 if a > len(b)
  if b == "" then return 'a' spaces
  else return b repeated 'a' times
 else take a elements from b

Fixed the surface level problem. As mentioned in the commit, the special case for strings will have to wait, since oK presently does not carry type information along with vectors- a zero length vector is just a zero-length vector:

  0#""
()
  5#""
(()
 ()
 ()
 ()
 ())
