Default variable values seem to be not supported by Template

[abotalov]

RFC6570 doesn't seem to have a concept of default values. But Template class has variable_defaults method so I would expect it it to work the same as here - http://msdn.microsoft.com/en-us/library/bb675245(v=vs.110).aspx (see "Default Variable Values" section)

But it doesn't work:

Addressable::Template.new('/test/{a=1}/{b=5}').variables
# => []
Addressable::Template.new('/test/{a=1}/{b=5}').variable_defaults
# => {}

Probably variable_defaults should be removed if it doesn't work.
