I agree that Ada is in many ways a superior language to C -- C is horrid -- but Emacs is written in C, and having a core feature of Emacs depend on Ada code is unlikely to be widely acceptable. Everyone compiling Emacs has a C compiler, but not everyone has an Ada compiler. Making an Ada compiler a prerequisite to compiling Emacs might be controversial. Perry (*C + elisp, but of course the elisp infrastructure is written in C and ships with Emacs.)
