Golang can't change template variable value

I have this code: http://play.golang.org/p/mPX1azLhlg but why I can't change my $foo value? How I supposed to do this?

This seems to have been updated in go1.11: https://golang.org/doc/go1.11#text/template

Modifying template variables via assignments is now permitted via the = token

So you need to change {{$foo := 1}} to {{$foo = 1}}

A variable's scope extends to the "end" action of the control structure ("if", "with", or "range") in which it is declared, or to the end of the template if there is no such control structure.
