Hi. Boosters,

I'm not too sure about this particular error( However I'll bet its a Concept 
error... whatever... Its certainly an error in the library implementation),. 
This is  an example of  mislocation that often occurs in C++.  (I often find the 
compiler outputs error messages fom standard libraries, only due to an error in 
my own code.). The XConcept Check and  enable_if( and mpl) libraries could help 
with this, if the library developer has  sufficient understanding, and if they 
are used. As it stands I dont believe that boost libraries take error checking 
adequately seriously. It would be useful if somebody picked up on 
error-checking in general and wrote a developers tutorial.  I am confident that, 
with designed-in error checking for all boost libraries,  the errors cited 
here( for instance) could be replaced with  something much more useful. For 
degree students... a useful topic... so take this up, combining theory of 
programming with prcatical day-to-day (economic)coding.
