I think this angle of view of word "modern" isn't wise.

IMO "modern" means supporting modern programming techniques:
 - webasm (there was a thread about webperl ,but I don't see it in recent perl)
 - multithreading (deprecated several years ago?)
 - llvm build (I want llvm@win32)
 - etc

The point "modern" === "use strict; use warnigns;" -- I don't buy it. 
Yet is too bloated, to my taste (so I don't use it, but this 
is another story)

I admit - the "use strict" feature is very good selling point of Perl.
But if the language does not support anything except "use strict" - then 
it is hardly useful.

This seems unwise to me.

Are there any modern languages that require some version on the top 
of the program?
Not in C++, Rust, Javascript - AFAIK
