It's all a matter of the way you think language semantics should work...
A statement like 'if', in an Algol-based language like Lua, works on statement
lists:
if { expression } { list to execute if true } { list to execute if false }
You really need a way of delimiting the statement lists. Lua and Pascal
believe that the syntax to do this belongs in the thing that is performing
the action --- if...then...else...endif. C and Javascript believe that it's
better to have seperate syntax for doing this; the thing that performs the
action operates on a *single* statement --- but you can wrap up a statement
list into a single statement.
Ultimately, this is purely a matter of personal preference, which means that
the only opinion that matters is that of the Lua devs. (As its their
language.) *My* personal preference is to go with the C-like style, but
that's only because I grew up on C.
