What good are evalf(level) and normal(level)?
by Richard B. Kreckel 06 Jan '16

06 Jan '16

Hi! Three weeks ago I've removed the 'level' argument of the eval() functions (on the C++11 branch). After all, if an object derived from basic is evaluated, it must evaluate its own structure, but not the one of expressions it contains - these are already evaluated. (This had become possible after elusive bugs in the automatic evaluation were fixed.) Now I wonder what the 'level' argument of evalf() and normal() are good for. The situation is slightly less clear than with eval(): After all, it *might* be useful to evalf/normal the expression's top level only without recursing down the directed acyclic graph. The question is: *Is* it a realistic use case to evalf/normal the expression to some level only? I do not see it. If anyone cares for the 'level' argument of evalf and/or normal, please respond and explain what it is used for. Otherwise, the 'level' argument will be removed by the end of this month. (Fact: This removal does not affect any of the regression tests.) All my best, -richy. -- Richard B. Kreckel <http://in.terlu.de/~kreckel/>
