This is true.  But this is a minor in my opinion. The root cause of this
situation is that linkers complain about multiply defined functions
- even when those functions are identical.  Maybe someday we'll
have smarter linkers - but until then this works quite well.  It does
require that one spend a little time explicitly considering code
instantiation.  But this isn't necessarily bad.  Letting the compile/linker
do all the work will lead to code bloat and compilation time problems.

I definitely agree with you - smarter linkers would be a big gift. Right now dealing with templates is generally a pain because of linker issues, and requires that one takes a lot of precaution to insure everything compiles/links smoothly.

I had the same problems when using the BGL last year, and also had to resort to manual template instantiation in the end.
