I've seen similar effects, not only with std.conv but with other 
modules as well. You just use a small part of one module but the 
compiler imports a lot of code.

It would be very interesting to know what happens underneath and 
how we can reduce the code bloat.

We should investigate what happens and we can use your example as 
case study.
