This has led the perl5 port for example to adopt variant names like perl5_16 which I've always found a little confusing. It has been nice that under the original naming scheme, one could assume that in many cases the variant name matches the name of the dependency that will be added. If you want to use the python27 port, you use a port's +python27 variant, etc.

Someone should do some tests. Make variants with dots, like "mysql5.1", and see if they work correctly. Can you install the port? Can you upgrade the port? Can you uninstall the port? What if other variants are also selected? If everything works fine we can relax this lint restriction.

A cursory glance at port.tcl suggests that periods are acceptable in variant names.
