 Description

in order to plot the integral of y  dy  from -1 to x fails (complaint of y being undefined), except if you define the expression as function and wrap it with eval(). Either fix this or provide a more specific error message with hint on how to succeed.

All 4 examples provided working fine in latest Nightly Builds :)

I'm going to close it.

This is one of the example that something must be changed in SMath core. One of the thing with confusion of eval() introduced. 

Many times I had the same thoughts that this "patching" things from the SMath basically symbolic and numeric evaluation causes the problem. Many times I was thinking that SMath should go completely numerical - but it seems it is inpossible due to the way it is working.
