All the optional examles use 'is_initialized()'. It seems like the non-idiomatic way:
if (name.is_initialized())
should be
if( name )
IMO.
I disagree, even though it is not my responsibility to define Boost idioms. ;-) The point is that being optional and being a boolean flag are two different things. Merging them under the same syntax saves keystrokes, but not the effort to review and understand the code that is already written. BTW - what about optional<bool>? optional<bool> optional_switch = ... if (optional_switch) { // the switch can be "false" here! } Isn't it confusing?
John Maddock has made the tool "bcp"
http://www.boost.org/doc/libs/1_35_0/tools/bcp/bcp.html
that allows one to easily make a boost library into an independent project.
I should have a look at this. -- Maciej Sobczak * www.msobczak.com * www.inspirel.com
