Returns the file name of this frame.
For example, using caller_locations.rb from Thread::Backtrace::Location
loc = c(0..1).first loc.path #=> caller_locations.rb
@return [Array<Vertex>] the vertices of {#graph} where ‘self` is a
{#descendent?}
@return [Array<Vertex>] the vertices of {#graph} where ‘self` is an
{#ancestor?}
@return [Object] the requirement that led to ‘requirement` being added
to the list of requirements.
Returns a new lazy enumerator with the concatenated results of running block once for every element in lazy.
["foo", "bar"].lazy.flat_map {|i| i.each_char.lazy}.force #=> ["f", "o", "o", "b", "a", "r"]
A value x returned by block is decomposed if either of the following conditions is true:
a) <i>x</i> responds to both each and force, which means that <i>x</i> is a lazy enumerator. b) <i>x</i> is an array or responds to to_ary.
Otherwise, x is contained as-is in the return value.
[{a:1}, {b:2}].lazy.flat_map {|i| i}.force
#=> [{:a=>1}, {:b=>2}]
