@section Querying variable bindings
Guile provides a procedure for checking whether a symbol is bound in the
top level environment. If you want to test whether a symbol is locally
bound in expression, you can use the @code{bound?} macro from the module
@code{(ice-9 optargs)}, documented in @ref{Optional Arguments}.

@deffn {library syntax} bound? variable
Check if a variable is bound in the current environment.
The procedure @code{defined?} doesn't quite cut it as it stands, since
it only checks bindings in the top-level environment, not those in local
