Version 7
Some time I use the wrong option for some function, but Mathematica never
complain. i.e. the expression is evaluated and no error or warning is given.
This can cause a problem, because what I expect to occur never does, and I
would then spend time to find why when Mathematica could have helped me by
easily pointing the problem if it did do more through option argument
checking.
Here is an example, I called Plot and Frame->True, but used TicksStyle
instead of FrameTicksStyle (earlier I had not had Frame->True there, then
added it later, forgetting to update the TickStyle).
The first call below goes through with no complain:
Plot[Sin[x], {x, -Pi, Pi}, Frame -> True, TicksStyle -> Directive[16]]
Plot[Sin[x], {x, -Pi, Pi}, Frame -> True, FrameTicksStyle -> Directive[16]]
I think I should have received an error saying that TicksStyle is not
"compatible" with Frame->True or something to this effect.
There are more examples like the above that one can find. I think all these
should be caught. It would save the user time in debugging.
Thank you,
