Comment 1:

Changing to Go1-Must to avoid breaking Go 1 programs later.
The fix should disallow = for assignment, even though it is used (probably accidentally)
in one test.  A simple, useful future addition would be to have = for reassigning
existing variables, so it is important that = not be equivalent to := now.
This is the test that will need changing:
    {"variable declared by template", `{{template "nested" $x=.SI}},{{index $x 1}}`, "[3 4 5],4", tVal, true},

Labels changed: added go1-must.
