I am having a huge compile performance problem trying to use mpl::begin for an mpl::vector of a large size -- the complexity seems to be far from constant (or even linear) time. The following example demonstrates it (I am using GCC 3.3.3 or 3.4.2)
Are you sure you're not seeing preprocessor slowness?
Almost :-) It takes almost nothing to generate 200 vector definitions. And then it takes about 10 seconds to do the begin (including preprocessor code that again generates 200 repetitions) But I can only verify it with the pre-processed code in a few hours... Regards, Arkadiy
