That proposal is smart, and very refreshing. Whatever the outcome, I
believe that's good food for thoughts :-)
As I personnally prefer keywords to symbols (in the context of Lua at
least), I'd rather have "from" be used instead of "<-" (since that's
how you read, why not write it that way?).
Injection on the other hand sounds less useful, and at the same time I
can't think of a good keyword to put in the place of your syringe
operator. A very bad one would be "sucks" (I'm not a native english
speaker and I can't find a better synonym):
tbl -< foo, bar, zig
becomes
tbl sucks foo, bar, zig -- from the globals
