Actually, there is no bug. Here's a console session:
>> f: func [a [any-type!]][print "f got called"]
>> f
f got called
>> f f f f f f 123 halt
f got called
f got called
f got called
f got called
f got called
f got called
>> f f f f f f 123
f got called
f got called
f got called
f got called
f got called
f got called
>> f f f f f f halt
>>
Note that Rebol evaluates the arguements to a function before calling the
function. In this case:
f f f f f f halt
the 'halt is evaluated just before evaluating the last (or first in
reverse order) 'f function. 'halt has the side effect of stopping execution
of Rebol, so the last 'f is not evaluated.
I hope that helps!
