Why does Corona give an error loading code that loads fine with lua?

I'm having problems with a specific line of code - building.transmitter:[operation](player, unpack({...})) that causes an error in Corona, yet this loads fine when it's run in Lua separately. I suspect it has something to do with the : being placed before the [operation] variable but I'm clueless why.

Specifically the module is written as,

local activate = {}

local function activate.transmitter(player, operation, ...) 
  building = player:getTile()   
  building.transmitter:[operation](player, unpack({...}))
end

return activate

The runtime errror that is appearing gives me 

"error loading module from file, '<name>' expected near '['"

Edit - WOW! I didn't notice that when troubleshooting this in Corona I changed some of the lines of code to identify the problem. I then mistakenly tested the edited code in Lua and it ran fine. I didn't realize the code wasn't the original until siffiejoe pointed out the interpreter getting an error as well. Sorry for the mistake.

maybe Corona uses older version of Lua which does not support this syntax. You can try workaround instead of 

building.transmitter:[operation](player, unpack({...}));

you can call

building.transmitter[operation](building.transmitter, player, unpack({...}));
