Gabriel Reid commented on CRUNCH-179:
-------------------------------------
Ok, as you're the person with that use case, you're probably the best placed to
decide if the hassle of creating a list of PCollections instead of using
varargs is worth it to not have to deal with the compiler warnings :-)
Actually, come to think of it, if we add a version that accepts a List,
Arrays.asList or Lists.newArrayList will probably be the most common way of
constructing that list, and they'll just result in the same compiler warning,
so I guess we'd best leave the varargs version alone.
> Add a properly typed union() method to PCollection and PTable

> I find myself slightly (albeit persistently) irritated by the warnings that
> come up in Eclipse as a function of using varargs for the union method on
> PCollection and PTable, so I wrote a union() method that takes a single
> argument and delegates to the regular union method. No functional change,
> just cleans up an irritating warning in my client code.
