 There are six ways to pass parameters that cover all use cases, that can be written before the parameter name:
 
-| Parameter ***kind*** | "Pass me an `x` I can ______" | Accepts arguments that are | Special semantics | ***kind*** `x: X` Compiles to Cpp1 as |
+| Parameter ***kind*** | "Pass an `x` the function ______" | Accepts arguments that are | Special semantics | ***kind*** `x: X` Compiles to Cpp1 as |
 |---|---|---|---|---|
-| `in` (default) | read from | anything | always `#!cpp const`<p>automatically passes by value if cheaply copyable | `X const x` or `X const& x` |
-| `copy` | take a copy of | anything | acts like a normal local variable initialized with the argument | `X x` |
-| `inout` | read from and write to | lvalues | | `X& x` |
-| `out` | write to (including construct) | lvalues (including uninitialized) | must `=` assign/construct before other uses | `cpp2::impl::out<X>` |
-| `move` | move from (consume the value of) | rvalues | automatically moves from every definite last use | `X&&` |
-| `forward` | forward | anything | automatically forwards from every definite last use | `T&&` constrained to type `X` |

 > Note: All parameters and other objects in Cpp2 are `#!cpp const` by default, except for local variables. For details, see [Design note: `#!cpp const` objects by default](https://github.com/hsutter/cppfront/wiki/Design-note%3A-const-objects-by-default).
