The documentation to
list_modify
indicates that one should "[u]sezap()
to remove values" from a list. This does not work in the expected way when attempting to remove a key-value pair whose value is a list:The first two examples above return an object identical to
list(bar = 3)
; the third is such that the call tolist_modify
is a no-op. This pull request fixes this behaviour. It also adds a unit test to cover this case.Issues: #776
