Two suggestions:

(1) Allowing the user-supplied function to accept _EXTRA keywords would also
be useful for other programs, such as QSIMP, QROMO, LMFIT and SVDFIT

(2) All these programs could be many times faster, if the user -supplied
functions were allowed to be vectorized! It goes against all my IDL
training to have to write functions that must a accept a scalar input and
return a scalar value.
