I reserve pragmatic for use as an adjective. It sounds very odd to me when used as a noun.
Added: I see, however, that the OED lists it as a noun, with the most recent citation from India and possibly the source of your query.
1914Indianapolis Star 6 Jan. 8/2 Whatever the findings of investigators are on the degree of legal responsibility for the building collapse at South Bend, the case appears as a sufficient answer to those pragmatics who see no utility in rigid building laws. 1999Times of India (Nexis) 12 Dec., Not a romantic who built castles in the air, but a pragmatic who, by sheer dint of hard work and forecast, built bridges where they were needed, without upsetting eco-harmony.
I'll check around for other such recent usages and report back if I find any.
