Hi Marc,

I can't recall if this is somewhere in the mailing list archive from before:

I recall that you indicated that parameter objects are expensive.

Would you mind describing/quantifying the average/worst case/best case cost for assigning a value to a parameter object by parameterization (|parameterize|), and for accessing a parameter object (load or store operation by invoking it as a closure)?

Parameter objects are very practical and have ample use scenarios, both high-level and relatively low-level.

Thanks,
Adam
