You must perform your test in a script file and 'do it to see the bug. The bug does not occur in a console session.

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! Andrew Martin Infinitely nested Rebol...
