The text/template package now correctly reports errors when a
parenthesized argument is used as a function.
This most commonly shows up in erroneous cases like
<code>{{if (eq .F "a") or (eq .F "b")}}</code>.
This should be written as <code>{{if or (eq .F "a") (eq .F "b")}}</code>.
The erroneous case never worked as expected, and will now be
reported with an error <code>can't give argument to non-function</code>.
