Comment(by ncalexan):
I don't understand this.
Why does the first match but the second not?
{{{
sage: ((x+y)).match(w0+w1)
{$1: x, $0: y}
sage: ((x+x)).match(w0+w1)
}}}
Can you explain the difference in these behaviours?
{{{
sage: ((x+y)^a).match((x+y)^a)
{}
sage: print ((x+y)^a).match((x+y)^b)
None
}}}
