filenames:
  foo.b   is a braced version of C
  foo.bb  is a braced version of C++
  foo.bh  is a braced header file, usually these are generated automatically
		  do we need a  foo.bbh  to distinguish C and C++ headers?
  if I ever learn objc, which would be a good idea, we can have foo.objb too!


adds ; to end of lines
adds { } around indented blocks
refuses to accept code with spurious spaces at start or end of line
blank lines must be indented to same depth as their block
. by itself on a line is ignored, and serves to mark indent depth
void return type and (void) arg are added to function declarations
() are added around for, while, switch, if, else if expressions
#include can be omitted, just write <foo.h> for example
# becomes // for shell-style comments
which keyword is switch with implicit breaks
goto labels are in first column, no need for :
a single indented word is a goto
case labels are in same column as switch/which, no "case" or ":"
numeric goto labels have "_" prepended automatically

coroutines / threads, . in first column indicates a yield point

add , at end of lines in enum, array/struct init, etc?
can omit () in func declaration? func call?
nested goto scopes?
interleaved case scopes? (how to do it!)
goto case?
includes at current indent
templates / macros
change pointer (esp. func pointer) syntax to something sane
include is just <...  not <...>?
support for static before function decl & auto-void?
implicit main() like python?  implicit exits(0)?
until, unless?
and, or?

loop with condition in the middle?  not unprecedented
- e.g. switch, if, else if, else

char line[MAXLINE]
int eof
loop
	readln(&line, &eof)
until eof
	writeln(&line)

repeat is an infinite loop, use break to exit it
