https://stackoverflow.com/insights/survey/2017/?utm_source=so-owned&utm_medium=blog&utm_campaign=dev-survey-2017&utm_content=blog-link#technology-most-loved-dreaded-and-wanted-languages
Lua is ranked 9-th in "Most dreaded Languages" list:
2/3 of developers who are currently using Lua express no interest in continuing to use it.

That's quite unexpected.
Probably, most of SO survey respondents are Lua newcomers.
What may be the reasons for their "moon fear"?

Maybe, deceptive simplicity (hidden complexity) of the language?
