Description
If I have an ArrayPartition involving a primitive type, such as a regular number, creating a similar through similar array fails.
Example:
using RecursiveArrayTools
a = randn()
b = randn(5,5)
arr_part = ArrayPartition(a,b)
similar(arr_part) # fails
ArrayPartitions are not designed for single numbers, but it would be nice if it also works for these types.

Research direction
Start at the ArrayPartition implementation and trace the similar(arr_part) dispatch for partitions containing a scalar and an array. Reproduce the Julia example from the issue, then add coverage for this case and confirm that similar(arr_part) succeeds for the shown ArrayPartition.
