How to assign function to Rebol struct member
I first define a function ADD:
add: func [ a [integer!] b [integer!] ] [a + b]
Then a struct:
s: make struct! [
sadd [ function! ]

But Rebol struct does not support the FUNCTION! datatype. How can I assign a function to a Rebol struct?

How can I get Rebol2 View running on Arch Linux?
There is a 64-bit version of Rebol2/Core available, but not of /View. If I try to execute the binary, it just says the file does not exist. What 32-bit libs do I need to install to get things running on Arch?
