Pass array to function, where one or more elements of the array have embedded spaces.
Goal: Have the embedded spaces respected in the array processed by the function.

Context:
Pass array to function, where one or more elements of the array have embedded spaces.
  Moreover, script seeks a nonnumeric result from function; uses command substitution to call the function.
  For the case without command substitution, see https://gist.github.com/jimratliff/ddcb5eb7e6fb184840e5dfd7e240c7ee

#	Script to determine empirically the extent to which a variable set in a script or
#		function can be seen by a hierarchically related function or script 
#	Specifically, (a) main script calls (b) function level1(), which calls
#		function level2(). (No arguments are used in any function call.)
#	Scalar variables are set in each component prior to any function call:
#		Main script sets $set_in_main_x, for x ∈ {A,B,C}
#		Function level1() sets $set_in_level_1_x, for x ∈ {A,B,C}
