Yes, I know about the minted package. And I have indeed used it. But
minted does not suit all my needs.

For each snippet of source code to be highlighted by pygments, minted
makes an individual call to the pigmentize application.

I am adding a new feature to minted to allow highlighting source code
inline (that is, the snippet is in a running line, not in a paragraph by
itself). With this feature I tend to hightlight many small pieces of
source code. Currently this has the effect of calling pygmentize many
times, making the compilation of the document too long. So I want to
study alternative implementations. The above procedure would call
pygmentex only once. So it would be more efficient.

I do not want to write a new package for that. I would just change
minted. If everything goes well, then I would propose the change to the
author of the minted package.
