that is quite easy to accomplish, here is how:
using: func [
[throw]
context-block [block!]
body [block!]
] [
foreach context context-block [bind body in context 'self]
do body
]
ctx1: context [a: 11]
ctx2: context [b: 12]
ctx3: context [c: 13]
using reduce [ctx1 ctx2 ctx3] [
print a
print b
print c
]
