Increment Operator

Pluto provides an easy way to increment variables using the prefixed ++ operator:

local x = 1
++x
print(x) -- 2

It can also be used as an expression:

local x = 1
print(++x) -- 2
-- x is still 2 at this point

In addition to being more handy due to being usable as an expression, it is also shorter than the equivalent Pluto code using compound operators:

local x = 1
x += 1
print(x) -- 2

And especially compared to the plain Lua approach:

local x = 1
x = x + 1
print(x) -- 2
