@karelpeeters' proposal is nice.

Copy code

buildSequence {
  yieldAll(heavySourceA())
  yieldAll(heavySourceB())
}.find { it == "MyString" }

heavySourceB

won't be called if

find

stops in the list given by

heavySourceA

. The

buildSequence

coroutine will suspend while iterating over

heavySourceA
