Support conditional transformation groups

[elfring]

Code rewriting should occasionally be performed at some places with several changes.
Thus different software adjustments would belong together.
Each adjustment depends on context information.
Only when a selected context was matched further change possibilities will be checked.
The context would usually consist of a header/prefix (or footer/suffix).
The successful matching of such data is therefore a precondition.

Possible case distinctions are in the development according to the approach “pattern match expressions”.
👀 I am looking for the support of change specifications accordingly.
I propose to group the desired data transformations then in a structured way.
