`declare function MV_INLINE<A..., R...>(inlineFunction: (A...) -> R...): (A...) -> R...`
will mark the passed function to be inlined where used.
Some limitations apply:
- The passed function cannot be variadic (i.e. no ... usage)
- The passed function cannot tailcall or otherwise recursively call itself.
- You must use this macro in it's specific form, i.e. `local <var> = MV_INLINE(function() ... end)`
## Valid Usage
```lua
local testFunc = MV_INLINE(function(start, endn)
local total = 0
for i = start, endn do
total = total + i
end
return total
end)
local testFunc2 = MV_INLINE(function()
return testFunc(1, 10), testFunc(11, 20), testFunc(1, 15)
end)
print(testFunc2())
```
