I was kind of wondering why they made that choice, given
compilers in many languages do not.

I think it is common to have a keyword used in function
definition - outside the
C-family. The Pascal family has keywords for function and
procedure declaration, as does Fortran. It looks like Cobol uses
the "function" keyword for when you call a function and
"function-id" for when you define it. Perl, Python and Ruby all
have a keyword for function definition.
Would this be a useful feature in D?
Everything else seems to have an annotation (e.g structs,
classes.) So why not functions?
What are people's thoughts about it?
I think keywords for functions may be to avoid or minimize the
difficulty C and C++ have with declaring (and deciphering the
declarations of) function pointers. Seems it also would have
prevented years of C++ having "the most vexing parse", where a
class instantiation can be confused with a function declaration.
