There is a pending PR waiting to be merged which will allow this by default. Until that is here, you need to `import typetraits`. > my input file contained integer that did not fit in 16 bits. I guess this was > due to the fact that I was using the const Sets (the ones in system, which you use without any import) are limited to `int16`. Hash sets (`import sets`) don't have this limit. For these kind of problems, it is even better to use int sets (`import intsets`).
