Thanks -- that should have been g_fluid_toplevel() instead of 
g_fluid_toplevel.

Normally, it's not useful to handle the fluid directly.  The fluid isn't the 
TOPLEVEL -- it's an opaque Guile construct, which can give you a TOPLEVEL if 
you ask it nicely.

You will notice that g_fluid_get_toplevel() returns a TOPLEVEL, as you'd 
expect.

g_fluid_toplevel() is a sort of "singleton function".  I gave it that name by 
thinking of it AS the fluid, rather than as a function which returns the 
fluid.

Does that make sense?
