Asterisk in val name using Scala

Question

Just saw an example that looks like the following:

val b_* = grater[Book].asObject(dbo)

What is the significance of the asterisk in b_* here? What's the name for it in Scala and what affect does it have on the outcome of b_?

it doesn't have any effect, it's just part of the variable name `b_*` — soulcheck, Sep 04 '13 at 13:53

Asterisk is valid in scala variable and value names, as are many other characters that are not allowed in in identifier names in Java or other C-like languages. See Valid identifier characters in Scala for more info.

However, just because it can be done doesn't mean it should be done. To my eye, it's not obvious at all what this value represents.
