Does it exist a generic coalesce function that returns the first value that is not nothing, e.g. a = nothing b = nothing c = "hello" d = nothing coalesce(a, b, c, d) should return “hello”.

First value different from nothing

It is aptly called something. Example:

julia> something(nothing, "hello", nothing)
"hello"

julia> something(nothing, nothing)
ERROR: ArgumentError: No value arguments present
