* The first parameter is a raw source map (either as a JSON string, or already

* have the following attributes:
*
* - version: Which version of the source map spec this map is following.
* - file: Optional. The generated file this source map is associated with.
* - sections: A list of section definitions.
*
* Each value under the "sections" field has two fields:
* - offset: The offset into the original specified at which this section
* begins to apply, defined as an object with a "line" and "column"
* field.
* - map: A source map definition. This source map could also be indexed,
* but doesn't have to be.
*
* Instead of the "map" field, it's also possible to have a "url" field
* specifying a URL to retrieve a source map from, but that's currently
* unsupported.
*
* Here's an example source map, taken from the source map spec[0], but
* modified to omit a section which uses the "url" field.

* into a non-hoisted node or the end of the list. A chunk is then converted
* into a single static vnode and replaces the hoisted expression of the first
* node in the chunk. Other nodes in the chunk are considered "merged" and
* therefore removed from both the hoist list and the children array.
