Since dynamic expressions are yet to be implemented, will a patch that takes ${cmd} as replacement input for regexprep but input of cmd should be a static string?

With Matlab, regexprep has an option to use ${cmd} in the replacement string to execute command cmd for each match:

https://www.mathworks.com/help/matlab/ref/regexprep.html#inputarg_replace

regexprep('aabb','ab','${fliplr($&)}')

Output should be 'abab' but Octave returns 'a${fliplr($&)}b'.
