When you need variable variables arrays are a natural fit.
The workarounds we all learned were only because HC didn't support
arrays. But now that we have them, we can make general-purpose
containers for any number of values stored by any name.
So instead of the funky:
do "put" && myText" && "into" && the foundChunk --or somesuch
...we can simply write:
put myText into tMyGeneralPurposeDataStore[someLabel]
