`if`, `elseif`, `for`, and `while` statements can be writtent without `do`, `then` or `end`, in which case they contain a single statement.
##### Suffixable string and table litterals
_Not in the latest release, install the `candran-scm-1.rockspec` version if you want this feature._
```lua
"some text":upper() -- same as ("some text"):upper() in Lua
"string".upper -- the actual string.upper function. "string"["upper"] also works.
-- Also works with calls, for example "string"(), but it isn't really useful for strings.
{thing = 3}.thing -- 3. Also works with tables!
[for i=0,5 do i*i end][3] -- 9. And table comprehensions!
-- Functions calls have priority:
someFunction"thing":upper() -- same as (someFunction("thing")):upper() (i.e., the way it would be parsed by Lua)
```
String litterals, table litterals, and comprehensions can be suffixed with `:` method calls, `.` or `[` indexing, or `(` functions calls, without needing to be enclosed in parantheses.
*Please note*, that "normal" functions calls have priority over this syntax, in order to maintain Lua compatibility.
### Preprocessor
Before compiling, Candran's preprocessor is run. It execute every line starting with a _#_ (ignoring prefixing whitespace, long strings and comments) as Candran code.
For example,
