'grab is OK for me. One variant I am always taking into account is:
collect-var: func [
[throw]
{Collects block evaluations.}
grab [word!] "grab-function name"
block [any-block!] "Block to evaluate"
/into dest [series!] "Where to append results"
/only "Insert series results as series"
] [...]
because the native SET function uses this calling convention too. The
advantage is, that this calling convention is referentially transparent,
i.e. it allows expression result as its 'grab argument value.
Request: please add this test to your test suite (it tests different
property than the tests you are using):
; test
collect x [
probe collect y [
foreach i [1 2] [
x: i
y: negate i
]
]
]
