You're probably using an older version of Rebol, that aggressively evaluates
paren! values. The beta versions don't do this. You can get "around" this by
using a different version of append like this:
>> source append
append: func [
{Appends a value to the tail of a series and returns the series.}
Series [series! port!]
Value [any-type!]
/Only "Appends a block value as a block."
][
either only [
insert/only tail :Series :Value
] [
insert tail :Series :Value
]
:Series
]
I hope that helps!
