Although you have to remember that his situation was considerably
different than ours.  He was in a position where he was designing a high
level language that had to be COMPATIBLE with C.  Our language is such
that a new person would have to learn the new, different, syntax
anyways.  Making them learn about the type system does not seem like much
of a stretch from learning the opcodes and how SSA form works, and how
everything ties together...

I would argue that because the lexical structure of the language is self
consistent, any person who spent a significant amount of time programming
in LLVM directly would understand how to do it without looking it up in a
manual.  The reason this does not work for C is because you rarely have to
declare these pointers, and the syntax is inconsistent with the method
declaration and calling syntax.

Very true.  If you're implementing an object oriented language, however,
remember that you have to do all the pointer to member function stuff
yourself.... so every time you invoke a virtual method one is involved
(instead of having C++ hide it for you behind "syntactic sugar").

Erm... excuse me but how is this the "old array syntax"?  If you are
arguing for consistency with C, you should be asking for 'type int []',
which is significantly different than the above (beside the above
introduces a new operator and duplicates information
needlessly).  Basically what I am suggesting is exactly the above without
the fluff.  So instead of:

       type [ int, int, ...]

you use:

       type [ int ]

This is not about function pointers.  This is about consistency in the
type system, and consistency with the rest of the language.  The point
above does not make arrays any more difficult to use, and makes the
structure of types much more obvious than the "c way".

Very true, but you seem to be advocating a completely different Type
system than C has, in addition to it not offering the advantages of clear
structure that the system I recommended does... so you seem to not have a
problem with changing this, just with what I change it to.  :)
