Bug #11107
Updated by nobu (Nobuyoshi Nakada) over 9 years ago
As below, lambda literal with do..end block can raise syntax error.
```
$ ./ruby -ve 'p ->() do a(1) do end end'
ruby 2.3.0dev (2015-04-26 trunk 50395) [x86_64-darwin14]
-e:1: syntax error, unexpected keyword_do_block, expecting keyword_end
p ->() do a(1) do end end
^
```
The error is not raised when I use {...} block or omit parentheses from method call in lambda.
NG cases:
```ruby ```
p ->() do a(1) do end end
p ->() do a() do end end
p 1, ->() do a(1) do end end
```
OK cases:
```ruby ```
p ->() do a 1 do end end
p ->() do a do end end
p ->() { a(1) do end }
p ->() do a(1) {} end
p ->() { a(1) { } }
```
