Jaroslav,

Lookup is an octave core function and so it would be better if the
decision was made to go with a compiled version of lookup to include it
in Octave itself rather than in octave-forge.. Can you tell us what the
improvements are.. Note that comments I've seen in the past about
compiled code is that there should be some justification of why its
better to use it rather than an m-file in terms of how often it is used
and the size of the speed improvement, since the effort in maintaining
C++ code is higher than m-files..
