This is mostly a question out of curiousity, but what is the utility of &-variables? I used to think that they were very useful, but then I learned that they could be substituted by $(TUP_CWD) and in the process be made much more powerful. For example, what is the meaningful difference between:
A = $(TUP_CWD)/file &B = file I know that internally &B actually references the database object, whereas $A is just a string, but in any context they'll ultimately resolve to the same string in the command. In addition, $A can be used in more places and can contain multiple pieces of information, e.g. A = $(TUP_CWD)/file1 $(TUP_CWD)/file2, where with &-variables you'd have to make two independent ones and type them out. Am I missing some utility of &-variables that I haven't considered?
