61590c4c44 disallow P.t for lowercase t and not our package P. 
implement hiding lowercase methods m in
signatures by adding in a hash of the package name
to the type hash code.

they are all gone.

9b8da82d72 Tweak code to make it easier to compile with gcc. 
+ Use macros to name symbols with non-ASCII characters.

5383e28ea0 change string([]byte) to pass array, rather than &a[0], 
to string convert.  if the byte array has length 0,
the computation of &a[0] throws an index bounds error.

for fixed size arrays, this ends up invoking arrays2d
unnecessarily, but it works.

This should build on OS X but may not.
