C'mon we are long past the days where tools had to written in $somelanguage. These are days where even things like compilers and databases are not being written in C.

If its of any help I think its time for the Unix community as a whole to sit down and self reflect. If people are beginning to think something like 'sed' as too level to use, then better job needs to be done to make them more accessible and usable. There are enough examples on this thread where people are saying that they look at sed as an API on top which a program needs to be built up on. And not a complete program in itself. Also shell is not a full fledged programming language.
