This is the best I can think of:
>> do-meth: func [obj [object!] meth [word! path! block!] args [block!]] [
[ do compose [(to-path compose [obj (to-block :meth)])
(args)]
[
]
>> do-meth obj 'f [1]
1 none none
>> do-meth obj 'f/ref [1 2]
1 true 2
>> do-meth obj compose [f (pick [ref []] random 2)] [1 2]
1 true 2
>> do-meth obj compose [f (pick [ref []] random 2)] [1 2]
1 none none
== 2
>> do-meth obj compose [f (pick [ref []] random 2)] [1 2]
1 none none
== 2
>> do-meth obj compose [f (pick [ref []] random 2)] [1 2]
1 none none
== 2
>> do-meth obj compose [f (pick [ref []] random 2)] [1 2]
1 true 2
