AFAIK, the documentation does not explicitly state whether
variables can store a callable entity or not. I believe the
current implementation in text/template assumes they cannot
though. The call builtin function is supposed to be used for
this purpose.
Template "{{0|$}}" should generate an error at runtime,
instead of a panic.
Similarly, template "{{0|(nil)}}" should not generate
a panic.
This CL aborts the sanitization process for a given pipeline
when no identifier can be derived from the selected node.
It happens with malformed pipelines.
We now have the following errors:
{{ 0 | $ }}
template: foo:1:10: executing "foo" at <$>: can't give argument to non-function $
{{ 0 | (nil) }}
template: foo:1:11: executing "foo" at <nil>: nil is not a command
Fixes #11118
