fails. This is because lexical_stream turns off white space skipping, and outfmt uses "[ ", ", ", and " ]" (with all those nifty spaces) as default formatting.

I've made a noise about this in the past. I strongly believe that current lexical_cast behaviour does not play nice with existing stream operators (which are commonly written to assume whitespace is skipped). There's no good reason for that, and lexical_cast should not use the "noskipws" flag.
