how would either of a and b be identified at runtime? I mean, you
write the code somewhere and it gets compiled. It's not like you're

against them.

what prevents D from having an eval function?
suppose someone modifies the DMD front-end to compile a string with
the
source code of a function in-memory, than this is processed by
something
based on DDL and what you get is an API call that takes source code in
a
string and returns a function pointer.
Even then it is *still* going to be compile time. Just a compile time
running at runtime... Ooohh, my heads's going to start hearing here in a
bit.
No it won't. you will call a standard library API at *runtime* with a
*runtime* string and get back a pointer to a function that you can call.
in fact Some Lisp compilers implement eval() exactly like that.
you're thinking in C++ terms. try thinking in Lisp...
