don't use \type, just escape the characters \{ \} etc or use symbolic 
names and use \tttf (or \tt for tje whole code fragment;  \type is 
overkill here an dmy do more hard than good

so you get something

\startVIMhightlighting
\vhl[#1]{....}
\stopVIMhighlighting

with

\def\startVIMhightlighting
  {\startlines \tt}

\def\stopVIMhighlighting
  {\stoplines}

\def\vhl[#1]#2%
  {\color[#1]{#2}}  % maybe even local colors when speed is needed

Even better, be more verbose:

\startVIMhightlighting
\vline{\vword[#1]{....}}
\stopVIMhighlighting

or even:

\startVIMparagraph
\startVIMline\VIMword[#1]{....}  ... \stopVIMline
\stopVIMparagraph

in that case you have way more control (line numbering/treatment, 
spacing etc)

[it's what i did with the scite exporter -- i output highligting in a 
compact XML where even spaces are tagged]
