d,d!Z xZ S )-AstroidBuildera Class for building an astroid tree from source code or from a live module.
The param *manager* specifies the manager class which should be used.
If no manager is given, then the default one will be used. The
param *apply_transforms* determines if the transforms should be
applied after the tree was built from source or from a live object,
by default being True.

( h(<== X%.88 >>W-FFF#+#4!)!8 /$- H H % $%#Hen== 1 !#Hu{D>> def x():
>>> def y():
>>> return 1 #@
The return statement will be extracted.
>>> class X(object):
>>> def meth(self): #@
>>> pass
The function object 'meth' will be extracted.
Expressions:
To extract arbitrary expressions, surround them with the fake
function call __(...). After parsing, the surrounded expression
will be returned and the whole AST (accessible via the returned
node's parent attribute) will look like the function call was
never there in the first place.
Examples:
>>> a = __(1)
The const node will be extracted.
>>> def x(d=__(foo.bar)): pass
The node containing the default argument will be extracted.
>>> def foo(a, b):
>>> return 0 < __(len(a)) < b
The node containing the function call 'len' will be extracted.
If no statements or expressions are selected, the last toplevel
statement will be returned.
If the selected statement is a discard statement, (i.e. an expression
turned into a statement), the wrapped expression is returned instead.
For convenience, singleton lists are unpacked.
:param str code: A piece of Python code that is parsed as
a module. Will be passed through textwrap.dedent first.
:param str module_name: The name of the module.
:returns: The designated node from the parse tree, or a list of nodes.
