scala - Type aliasing to avoid name clash in type refinement -

-

can use aliasing don't need change either of type parameter/member in following name clash situation:

trait bar {   type }  trait foo {   def get[a]: option[bar { type = }]  // "illegal cyclic reference" }

i know can write

trait foo {   def get[a1]: option[bar { type = a1 }] }

but prefer not change type name.

you e.g. this:

trait bar {   type }  trait foo {   type m[x] = bar { type = x }   def get[a]: option[m[a]] }

or inline:

def get[a]: option[({ type x[y] = bar { type = y }})#x[a]] = ???

or, if prefer:

def get[a]: option[({ type a1 = a; type x = bar { type = a1 }})#x] = ???
