Recent compilers are warning about pessimizations

[gotnone]

I have been playing around with rangeless as a faster compiling alternative to std::ranges and ranges-v3. I have been getting some compiler warnings that there are redundant or pessimizing moves in fn::transform and in fn::take_while. Would you consider removing the unnecessary std::move wrappers on lines 1592 and 1846? See this example. Thanks.

Thanks for the suggestion! I'll have a look at it next week.
