[fpc-pascal] How can I get a typeinfo by address?

I need to call a method dynamically by its name over string and pass some
parameters to it. OK, I don't know if it is possibly in the current version
of the compiler, but I'm trying to do something like this:
TMethodInvoker.Invoke(VMyObj, ['Param 1', 'Param 2', 1, True]);
I already get some paramerter informations using this code, that prints
all parameters and its types using RTTI.
So I have a question: how can I get the method typedata looking for it in
the VMT? Please see this:
Prints the same address. But:
TI := TypeInfo(@TMyObject.Test);
TI := TypeInfo(TMyObject.MethodAddress('Test'));
Prints different results.
How System.TypeInfo retrieve the typeinfo from my @TMyObject.Test address?
It is done by the method address so?
I took a look at the TRTTIWriter class and also in the VMT, but I don't
know how the compiler handles this informations internally, so sorry it
this question sounds nonsense. =P
