     In addition to the functions listed below, the `calc` module also defines
     the constants `pi`, `tau`, `e`, and `inf`.

+    A module that contains all globally accessible items.
+
+    # Using "shadowed" definitions
+    The `std` module is useful whenever you overrode a name from the global
+    scope (this is called _shadowing_). For instance, you might have used the
+    name `text` for a parameter. To still access the `text` element, write
+    `std.text`.
+
+    ```example
+    >>> #set page(margin: (left: 3em))
+    #let par = [My special paragraph.]
+    #let special(text) = {
+      set std.text(style: "italic")
+      set std.par.line(numbering: "1")
+      text
+    }
+
+    #special(par)
+
+    #lorem(10)
+    ```
+
+    # Conditional access
+    You can also use this in combination with the [dictionary
+    constructor]($dictionary) to conditionally access global definitions. This
+    can, for instance, be useful to use new or experimental functionality when
+    it is available, while falling back to an alternative implementation if
+    used on an older Typst version. In particular, this allows us to create
+    [polyfills](https://en.wikipedia.org/wiki/Polyfill_(programming)).
+
+    This can be as simple as creating an alias to prevent warning messages, for
+    example, conditionally using `pattern` in Typst version 0.12, but using
+    [`tiling`] in newer versions. Since the parameters accepted by the `tiling`
+    function match those of the older `pattern` function, using the `tiling`
+    function when available and falling back to `pattern` otherwise will unify
+    the usage across all versions. Note that, when creating a polyfill,
+    [`sys.version`]($category/foundations/sys) can also be very useful.
+
+    ```typ
+    #let tiling = if "tiling" in dictionary(std) {
+      tiling
+    } else {
+      pattern
+    }
+
+    ...
+    ```
