Lua does too, for literal tables and strings being sole argument you can omit parentheses. But to call method on a literal you need to add them.

> print("OK")

> print "OK"

> ("OK %d"):format(1)

I've seen some funky (ab)use of these, people using literal strings and tables and functions named class and similar to do:

> class "Something" {

> -- ...

> }
