#53 Plomino chokes on '_' (underscores)

[Jean Jordaan]

The name munging of generated indexes assumes that no view or column name will contain underscores (e.g. in PlominoCatalog.recordify).
This is a needless and arduous restriction (and not documented either; in fact, Plomino itself uses Plomino_Authors).
At least, the symbol used should be changed to something not commonly used in identifiers, e.g. one (or more) of ~,;!*
A better solution would be not to rely on name munging.
