It is told in help, that
Infix[expr,h,precedence,grouping] can be used to specify how the
output form should be parenthesized.
but actually it doesn't work:
Format[EClass[x___]] := Infix[{x}, "=", 290, None]
In[40]:= EClass[a, b, c]
Out[40]= Infix[{a, b, c}, "=", 290, None]
while
In[65]:= Format[EClass[x___]] := Infix[{x}, "="]
In[66]:= EClass[a, b, c]
Out[66]= Infix[{a, b, c}, "="]
works.
So how to specify precedence for infix format?
Thanks.
