I personally often use such calls in my micro-DSLs. Like this:
I find this style to be shorter and to better express
"declarativeness" of the code.
Also it is arguable simpler for non-programmers to comprehend in some cases.
"Non-weird" equivalent would have too many braces to my taste:
local tmp = foo("name")
I believe Lua would be a bit less elegant without parenthesis-free calls.
