I think the syntax should just be changed from concat(Traversal) to
concat(Traversal...) which would let you work around this issue by using
constant():
g.V(3).as('a').values('code').concat(constant(' is in '),
select('a').values('city'))
This would address the symmetry problem with concat(String...) without
having to open up concat(Object...) (at least not yet). I think format()
could be a neat step and there was an open issue for it at one point:
https://issues.apache.org/jira/browse/TINKERPOP-2334
i'd closed it once i saw that dave had suggested these lower level string
functions. i'd like to see the lower level functions added first and then
talk about bringing back to the format() idea.
