AH> In other words, "continue" is definitely still at the top of my Lua wish list.
and in my wish list too, code looks much simpler using continue, just
compare:
1. using continue
for i,j in pairs(some_table) do
if (condition0(i,j)) then
continue
end
if (condition1(i,j)) then
break
end
if (condition2(i,j)) then
continue
end
foo ()
end
2. without using continue
for i,j in pairs(some_table) do
if (not condition0(i,j)) then
if (condition1(i,j)) then
break
end
if (not condition2(i,j)) then
foo ()
end
end
end
3. emulating continue
local function cycle (i,j)
if (condition0(i,j)) then
return (true)
end
if (condition1(i,j)) then
return (false)
end
if (condition2(i,j)) then
return (true)
end
foo ()
return (true)
end
for i,j in pairs(some_table) do
if (not cycle(i,j)) then
break
end
end
