# Element 0: zero is: 4 long. # Our marker element
# Element 1: ’Hello ${Me}’ is: 13 long. # Our "$(_pls ’...’ )"
# Element 2: Hello ${You} is: 12 long. # Quotes are missing
# Element 3: \’Pass: \’ is: 10 long. # ${pw} expanded to nothing
# Now make an assignment with that result.

for (( i=0 ; i Expansion required, strip the quotes.
# $( ... ) -> Replace with the result of..., strip this.
# _pls ’ ... ’ -> called with literal arguments, strip the quotes.
# The result returned includes hard quotes; BUT the above processing
#+ has already been done, so they become part of the value assigned.
#
# Similarly, during further usage of the string variable, the ${Me}
#+ is part of the contents (result) and survives any operations
# (Until explicitly told to evaluate the string).
# Hint: See what happens when the hard quotes ($’\x27’) are replaced
#+ with soft quotes ($’\x22’) in the above procedures.
# Interesting also is to remove the addition of any quoting.
