Mar 6	comment	How to use Function[] in MatchQ[] and control argument's evaluation? Is there a way to make `verbatimeNumericQ` effectively test `2*3` instead of literal `x`? `In[187]:= MatchQ[Unevaluated[2+3],_?(Function[{x},NumericQ@Unevaluated@x,HoldAllComplete])‌] Out[187]= False` is correct.

Mar 6	comment	How to use Function[] in MatchQ[] and control argument's evaluation? The answer to the referred question doesn't answer all questions asked here. Using parentheses makes the output `True`. How to get a `False` result then? Because `2*3` while unevaluated is not `NumericQ` `True`. What's the best way to use a Function[] in MatchQ[] to validate an expression by pattern matching its "unevaluated" form?

Mar 2	comment	How to draw a pane with rounded corners? The following works: `Framed[Pane[ Style["XXXX", FontSize -> 11], ImageMargins -> 1, Alignment -> {Center, Center}], Background -> Pink, RoundingRadius -> 10, FrameStyle -> None]` Is `ImageMargins -> 1` there? Is there a way to get the spaces above and below text narrower?
