 Since `defn` returns a standard TS/JS function, all arguments will be
 automatically type checked at call sites (in TypeScript only).
 
+#### Function arguments
+
+Function argument lists are given as arrays, with each item either:
+
+1. an AST type string, e.g. `"float"`
+2. a tuple of `[type, name?, opts?]`, e.g. `["vec2", "bar", { q: "out" }]`
+
+If no name is specified, an auto-generated one will be used. Generally,
+this is preferable, since these names are only used for code generation
+purposes and in most cases only need to be machine readable...
+
+The body function (last arg given to `defn`), is called with
+instantiated, typed symbols representing each arg and can use any name
+within that function (also as shown in the above example).
+
+See `SymOpts` interface in
+[api.ts](https://github.com/thi-ng/umbrella/tree/master/packages/shader-ast/src/api.ts)
+for more details about the options object...

 const sinc = (x: FloatTerm, k: FloatTerm) =>
-    div(sin(mul(k,x)), mul(k, x));
+    div(sin(mul(x,k)), mul(x, k));
 ```
 
+**Performance tip for INLINE functions only:** Since the `FloatTerm`
+type (or similarly any other `XXXTerm` type) refers to any expression
+evaluating to a `"float"`, in some cases (like this `sinc()` example) it
+might be better to only accept `FloatSym` arguments, since this ensures
+the arg expressions are not causing duplicate evaluation. For example:
+
+```ts
+sinc(length(mul(vec3(1,2,3), 100)), float(10));
+```
+
+...will be expanded to:
+
+```ts
+div(
+    sin(mul(length(mul(vec3(1,2,3), 100)),k)),
+    mul(length(mul(vec3(1,2,3), 100)), k)
+);
+```
+
+...which is not desirable.
+
+If, however, the inline function asks for `FloatSym` args, the caller is
+forced to supply variables and so is also responsible to pre-define
+them... Alternatively, the function could be re-defined via `defn` to
+avoid such issues altogether (but then causes an additional function
+call at runtime - nothing comes for free!).
