Select syntax pretty useful

I just made a nice discovery (undocumented from what I can make out)
If you have an ets table and want to retrieve strings which start with a
certain prefix you can do:
1>E=ets:new(sean, [bag]).
10
2>ets:insert(E, [{sean, "sean", 1}, {sean, "bean", 2}]).
true
3>A="se".
"se"
4>ets:select(E, [{{sean, A++'_', '_'},[],['$_']}]).
[{sean, "sean", 1}]
This is pretty nice, and it means we can do our current app without needing
some bloated expensive RDBMS product :-)
My thanks to the R8 team,
Sean
