I concur with the implicit conversion being consistent with Fortran's

Clearly any system striving to be compatible with an existing user  
base (viz. any system likely to be successful) is going to have to  
keep the old format around (perhaps indefinitely). The IBM zSeries as  
an example (traditional hexadecimal fp, IEEE fp as well as  
decimal ;>). So I don't think characterizing a two radix chip (or  
system, why the number of chips is relevant to the discussion eludes  
me) as insane is reasonable.
