[Boost-users] string_algo no replace_if

Dear all

I was requesting an 'erase_if' a while ago, and now I ran into a 'replace_if' 
problem. So after spendig 2 hours in the documentation, I finally found on www 
('[string_algo] replace repeated char with single instance?') that one should 
use the 'find_format_all':

boost::find_format_all(str, boost::token_finder(boost::is_any_of("ab")), 
boost::const_formatter("c"));

But wouldn't it be better to make a 'replace_if' shortcut solely for the 
purpose of documentation reasons:

boost::replace_all_if(str, boost::is_any_of("ab"), "c");

I think that most people find the last line easier to read and comprehend than 
its (more powerful) 'find_format' cousin. The string_algo library is nice but 
I get lost more than once. Especially find, replace, erease with predicates 
are often used by us. However direct use seems not possible.

wkr,
me
