Using n-dimensional arrays in build scripts is a rare usecase. you can easily switch to AWK if this fits more. But using Perl or Python should be avoided, because it adds more complexity to the dependencies and leads to more headache when maintaining:
Just to be sure, are you saying that we should also avoid indexed array in bash? It is possible to create n-dimensional arrays with indexed array. The main reason for this is to be sure that I am on the right track.
IMHO, every script language has it own pros and cons. But for a complex build system (such as buildroot/openwrt), consistency, compatibility and dependencies are difficult to maintain and also makes difficult for testing (the number of possible test required to ensure the compatibility increases exponential as we add more dependency). For example, RHEL5 uses bash version 3.x which does not support associated array. Sometimes some of the dependency can be avoid and best to avoid from maintainers point of view.
