A (small) correction: it may exist syntactically, ``` $ ruby -c -e 'X=1; module X; end' Syntax OK ``` but a `TypeError` will be raised at runtime if it is not a `Module`. ``` $ ruby -e 'X=1; module X; end' Traceback (most recent call last): -e:1:in `

The higher level module is derived from its name in a string. This works in one case and gives an unexpected syntax error in another case. ``` failing_meta:4: syntax error, unexpected '\n', expecting &. or :: or '[' or '.' failing_meta:8: syntax error, unexpected keyword_end, expecting end-of-input ``` ---Files-------------------------------- no_meta (72 Bytes) working_meta (82 Bytes) failing_meta (95 Bytes) -- https://bugs.ruby-lang.org/
