Conisder \setupcolors[state=start] \setuptyping[option=anything] %Any value that is not a valid option % none, color, normal, commands, slanted \starttext \startbuffer $\sum_{i=1}^n \frac{1}{2} n \cdot (n+1)$ \stopbuffer \typebuffer \stoptext The text is typed in color. I gave an invalid option and expected it to have no effect, but was pleasantly surprised that it gives color output. There is nothing in the definition of \setupcommonverbatim in core-ver.tex to suggest such a behaviour. Is this a bug or a feature?
