#set <varname> [=] <value>

To be valid, varnames must match the JavaScript regex /_[0-9A-Z][_0-9A-Z]*/.

<value> can be a raw value, varname, or expression. If you don't specify the value, it is set to undefined.

You can omit the equal sign (=).

#if <expression>

Includes the block that follows if <expression> is not falsy.

You can nest multiple #if.. blocks.
