1benefits of translucent records for building development toolshistory

It's important to be able to build development tools that operate on all types of records, not just one in particular. For example, if I want to build a debugger that is able to print out the contents of record structures in a uniform way, I need a standard way to ask any record for its contents, for its RTD, etc. The debugger should not have to be extended every time a new record type is defined. While most programs may not make use of this facility, its controlled use is powerful and useful.
