If I have a magic vim regex in a string literal, is there a utility to convert the whole regex into an alternative representation that uses a different magic mode, so I could paste that equivalent regex into source code?

For instance, if I want to convert this magic-mode pattern:

'\m-\=\<\d\+L\=\>\|0[xX][0-9a-fA-F]\+\>'

to very-magic-mode to make it more readable, something like:

'\v-=<\d+L=>|0[xX][0-9a-fA-F]+>'

I often make mistakes trying to convert them by hand.
