It appears that J 6.01c introduced an undocumented change: now <.@:f
tries to produce extended results for extended argument (previously
only <[EMAIL PROTECTED] made this attempt). Example:
9!:14''
j601/2006-11-17/17:05
] r=: <.@:%: 2 * 10 ^ 56x
14142135623730950488016887242
This produced an error in the deep, dark depths of some of my code
(which had specifically used <.@: instead of <.@ because the
latter was apt to produce nonce errors).
The behavior of the construct [: <. f has not changed, so it
provides a workaround.
Was this discussed on the forums? Will it be documented in Section II G?
