{{#with}} renders a subsection with a new context added to the can-view-scope.
For example:
TEMPLATE:
{{#with person.address}}
Street: {{street}}
City: {{city}}
{{/with}}
DATA:
{person: {address: {street: "123 Evergreen", city: "Springfield"}}}

Street: 123 Evergreen
City: Springfield

TEMPLATE:
{{#with person.address}}
Street: {{street}}
City: {{city}}
{{/with}}
DATA:
{person: {}}

Street:
City:
