In Lua, we do write "{1,2}" rather than "table 1, 2 end".  Given that functions
are fundamental data type, like tables, there is consistency in using
punctuation to denote functions, particularly when used as lambda expressions.

Approaches for syntactically lightweight closures are also discussed in [1].
