[perl #117695] "It is possible to alias ... by using the term syntactic category" -- broken

[Christian Bartolomaeus via RT]

This now dies with "Term definition requires an initializer":

$ perl6-m -e 'my \term:<a> = 1;'
===SORRY!=== Error while compiling -e
Term definition requires an initializer
at -e:1
------> my \term⏏:<a> = 1;
    expecting any of:
        scoped declarator

It works with STD:

$ viv -c -e 'my \term:<a> = 1;'
 syntax OK
