Personally, I don't see the necessity, but if some additional
separators in variable names are really useful for some people, ksh93
namespaces might be newly supported. ksh93 supports namespaces of
variables separated by dots.

ksh$ a=1
ksh$ a.hello=2
ksh$ a.world=3
ksh$ echo ${a.hello}
2
ksh$ echo ${a.world}
3
