What if operator precedences were specified as a partial order instead

Hi -
I'm wondering if it is possible to construct a methodical procedure to
assign a fixity to symbolic operators so that we could get rid of the need
for user defined fixites. User defined fixities are an enormous problem for
an interactive editor, because it is not possible to construct a

Perhaps the editor could assume a default precedence when the
user-defined precedence is not yet available. Preferably, the editor
would also somehow yell at the user to indicate that it is making such
an assumption.
I think it's unreasonable to tie programmers' hands for the sake of
