+ The current language affects expression parsing and evaluation
+ (FIXME: it might be cleaner to make the evaluation-related stuff
+ separate exp_opcodes for each different set of semantics. We
+ should at least think this through more clearly with respect to
+ what happens if the language is changed between parsing and
+ evaluation) and printing of things like types and arrays. It does
+ *not* affect symbol-reading-- each source file in a symbol-file has
+ its own language and we should keep track of that regardless of the
+ language when symbols are read. If we want some manual setting for
+ the language of symbol files (e.g. detecting when ".c" files are
+ C++), it should be a seprate setting from the current_language. */
