Description Gael Guennebaud 2019-01-17 15:33:51 UTC
Currently expr.eval() immediately evaluates the expression and returns a plain object. In some (many?) cases it is desirable to only flag a subexpression that it should be evaluated within a temporary at evaluation time.

This was initially discussed in bug 505.
