validate that function invocations are carried out using the correct
sequence of parameters. Furthermore performing the checks at compile
-time rather than at run-time (aka every time the function is invoked)
will result expression evaluation performance gains.
will result in expression evaluation performance gains.
Compile-time type checking can be requested by passing a string
representing the desired parameter sequence to the constructor of the
igeneric_function. The following example demonstrates how this can be
done:

One further refinement to the type checking facility is possibility of

by using a wildcard '*' at the end of the sequence definition.
