Given the file:
{{{
foo = 1
a = ()
foo = 1
b = ()
foo = 1
}}}
You get the error message:
{{{
Uniplate.hs:3:0:
Multiple declarations of `Main.foo'
Declared at: Uniplate.hs:1:0
Uniplate.hs:3:0
Uniplate.hs:5:0:
Multiple declarations of `Main.foo'
Declared at: Uniplate.hs:1:0
Uniplate.hs:5:0
}}}
Instead of the much simpler:
{{{
Uniplate.hs:5:0:
Multiple declarations of `Main.foo'
Declared at: Uniplate.hs:1:0
Uniplate.hs:3:0
Uniplate.hs:5:0
}}}
This also happens with multiple class definitions, but if you give
multiple type signatures then the error message is properly merged.
