The overloaded brackets match objects in the hierarchy through calls
of igetid(), with some processing before and after it. So it is mostly
up to igetid's way of finding identifiers.

The matches are not necessarily of single objects:

IDL> s=surface(/test,axis_style=2)
IDL> help,s['*axis*']
<Expression> OBJREF = Array[12]
IDL> foreach el,s['zaxis'] do print,el.name
Axis 2
IDL> foreach el,s['zaxis*'] do print,el.name
Axis 2
Axis 5
Axis 8
Axis 11
