On the current implementation if you try to convert "700" to an int you will
get 700. If you want to take it as the representation of other than a
decimal number you will need to use explicitly a specific library that
provide it, as Boost.Coerce could do.

If the Boost community consider that there is no good default behavior fro
string to int conversion I will remove this specializations. 

Anyway, what is the result of

  coerce::as(*int*)("700");

?
Best,
Vicente
