Cannot redefine a function when contains eval() - function not defined error

When a function contains eval(), it cannot be defined again (it is defined and stored, but evaluation is no more possible). Worked in SS 0.97.*.

Yes, there are several functions such as if(), sum(), product(), diff() and maybe couple others - these functions supported to work with undefined variables inside. That is why they behave differently against to all other ones. I know about this issue and will address it a bit later.

Closing this ticket as an initial issue is fixed now.

True, eval(...) is no more an issue :)

wondering if if(...) can be cured in the same way (and other functions that acts in the same way, if they exists).

eval() part seem to be fixed - I suppose with SS-167?

Ah, you are right, it didn't work neither in 0.97! The same happens with if/else....

Now I'm really confused because Jean has posted a file that wored in 0.97.5346 and doesn't work anymore in 0.98. One of the issues was about redefinition of functions based on if/else (and they should behave in the same way in both the versions),

The reason is that if eval(..) cannot be calculated numerically it always raise an error. So, line with definition f(x):eval(2+x) just ignored by SMath Studio. As I remember we have this behavior from the first release of eval(..) function.

Do not work in 0.97.5154 and 0.97.5890 as well.
