Weirdness is subjective. If you look at lisp for the first time coming from other languages it will be weird.
PHP had glaring issues for years, but they started to clean up the language around 7.x.
JavaScript was effectively a toy but grew up in a hurry when Node pushed ecmascript forward and into a well paced release pattern.
To me all weirdness IS poor design.

Fast it sure is, for an interpreted language.
On "clean and tight" I beg to differ. I find it an unholy mess: the language, the stdlib and the ecosystem.
