The logical inverse of ‘capture_last_end_same_indent`
When there is an invalid block with an ‘end` missing a keyword right after another `end`, it is unclear where which end is missing the keyword.
Take this example:
class Dog # 1 puts "woof" # 2 end # 3 end # 4
the problem line will be identified as:
> end # 4
This happens because lines 1, 2, and 3 are technically valid code and are expanded first, deemed valid, and hidden. We need to un-hide the matching keyword on line 1. Also work backwards and if there’s a mis-matched end, show it too
Returns a new lazy enumerator with the concatenated results of running block
once for every element in the lazy enumerator.
["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:
x
responds to both each and force, which means that x
is a lazy enumerator.
x
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}]

If a block is given, returns a lazy enumerator that will iterate over the given block for each element with an index, which starts from offset
, and returns a lazy enumerator that yields the same values (without the index).
If a block is not given, returns a new lazy enumerator that includes the index, starting from offset
.
