True, a backslash within a string or character is not a sufficient alert. 
However, a backslash within a symbol is. For example, although it's relatively 
common to see strings like this in Elisp source code:

   "color=\"blue\""

it's extremely uncommon to see symbols like this:

   color=\"blue\"

and so if one sees such a symbol (possibly with some other character in place of 
the " marks, possibly not) one will easily know that something odd is going on.
