component x
import List.{...}
import Set.{...}
export Executable
run(args:String...) = do
singleton[\String\]("1")
end
end
Both List and Set have a singleton[\E\](x:E) method. The output is:
x.fss:7:4-24: No matches for instantiation of overloaded {
PENDING BELOW
* singleton[\E\](e:E):List[\E\]/home/kazzmir/fortress/trunk/Library/List.fss:490:0-494:5
* singleton[\E\](x:E):Set[\E\]/home/kazzmir/fortress/trunk/Library/Set.fss:75:0-78:3}:OverloadedFunction with (String)
If the type parameter is left off, a slightly different error message is produced:
component x
import List.{...}
import Set.{...}
export Executable
run(args:String...) = do
singleton("1")
end
end
Output:
/home/kazzmir/fortress/trunk/tmp/x.fss:7:4-18: Failed to find any matching overload, args = ("1"), overload = {
PENDING BELOW
* singleton[\E\](e:E):List[\E\]/home/kazzmir/fortress/trunk/Library/List.fss:490:0-494:5
* singleton[\E\](x:E):Set[\E\]/home/kazzmir/fortress/trunk/Library/Set.fss:75:0-78:3}:OverloadedFunction
