] | Prepares to check the body of a node to see if it's a block statement.
@param {ASTNode} node The node to report if there's a problem.
@param {ASTNode} body The body node to check for blocks.
@param {string} name The name to report if there's a problem.
@param {{ condition: boolean }} opts Options to pass to the report functions
@returns {Object} a prepared check object, with "actual", "expected", "check" properties.
"actual" will be `true` or `false` whether the body is already a block statement.
"expected" will be `true` or `false` if the body should be a block statement or not, or
`null` if it doesn't matter, depending on the rule options. It can be modified to change
the final behavior of "check".
"check" will be a function reporting appropriate problems depending on the other
properties. | [
