Hi, don't know if it's still a topic for you but here is a "workaround", you are
right that there is no native way to extend an object.
extend-object: func ['obj-word [word!] 'word [word!] value [any-type!] /local
the-obj][
all [not object? the-obj: get obj-word make error! "No object provided."]
if in the-obj word [
set in the-obj word value
return the-obj
]
set obj-word make the-obj reduce [to-set-word word value]
]
use like:
extend-object objectoextend newword newvalue
