Keeps track of what lines have been added to blocks and which are not yet visited.
Given that we know our syntax error exists somewhere in our frontier, we want to find the smallest possible set of blocks that contain all the syntax errors

Invoked by Ruby’s core methods to run a blocking operation in a non-blocking way.
Minimal suggested implementation is:
def blocking_operation_wait(work) Thread.new(&work).join end
Returns the source encoding name as a string.
Returns the source encoding name as a string.
offline mode. read name=value pairs on standard input.
Yields to a block and preserves the previous set of objects being printed.
Check whether the object_id id is in the current buffer of objects to be pretty printed. Used to break cycles in chains of objects to be pretty printed.
Adds the object_id id to the set of objects being pretty printed, so as to not repeat objects.
Removes an object from the set of objects being pretty printed.
Creates a self-signed certificate with an issuer and subject from email, a subject alternative name of email and the given extensions for the key.
Turns email_address into an OpenSSL::X509::Name

If the stream begins with a BOM (byte order marker), consumes the BOM and sets the external encoding accordingly; returns the result encoding if found, or nil otherwise:
File.write('t.tmp', "\u{FEFF}abc") io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => #<Encoding:UTF-8> io.close File.write('t.tmp', 'abc') io = File.open('t.tmp', 'rb') io.set_encoding_by_bom # => nil io.close
Raises an exception if the stream is not binmode or its encoding has already been set.
Sets the encoding according to the BOM (Byte Order Mark) in the string.
Returns self if the BOM is found, otherwise +nil.
