Use "&" in a key, for example the "G&T" of me

From a viewpoint of the "get property /set property" syntax
"unexpected results" sounds convincing here, but, TMHO, it is
exactly what I would expect from a **viewpoint of array syntax**.
put "minimal" into catness
--> Then the next two lines
set the minimal of me to "very much" --(1)
set the "minimal" of me to "very much" --(2)
--> are equivalent and create the same key "minimal".
--> As catness is "minimal" and is NOT empty, this is also equivalent to
set the catness of me to "very much" --(3)
--> what is, as usual when quoting, equivalent to
set the "catness" of me to "very much" --(4)
--> Four equivalent commands (1)-(4) result in the same key "minimal".
--> And it["catness"] is empty, correctly.
get the customProperties of me
put it["catness"] &"/"& it[catness] &"/"& it["minimal"] &"/"& it[minimal]
put cr & the keys of it after msg
