Re: Shorthand for appending to a table (was Re: 5.2 feature list?)

[Tim Gogolin <tgogolin@...>]

Right; I understand this point of view.  The problem though is that  
table.insert(t, v ) has a hash lookup penalty and a function call  
penalty.

local table_insert = table.insert

will get rid of the hash lookup, but the function call is somewhat  
painful inside a tight loop.

I've actually found myself making local tables named "t" (where  
otherwise I had more meaningful names), in order to make the append  
easier to read... which is unfortunate.
