[Python-Dev] Python 3.x and bytes

In this case, I think the intent would be better captured with

def ASCII(c):
    return c.encode('ascii')

EOH     = ASCII('\r') # 0D
CHAR    = ASCII('C')  # 43
DATE    = ASCII('D')  # 44
FLOAT   = ASCII('F')  # 46
INT     = ASCII('I')  # 49
LOGICAL = ASCII('L')  # 4C
MEMO    = ASCII('M')  # 4D
NUMBER  = ASCII('N')  # 4E

This expresses the intent that a) these are really byte values,
not characters, and b) the specific choice of byte values was motivated
by ASCII.
