 Compiler internals
 ==================
 
+Differences from ``go``
+-----------------------
+
+  * A whole program is compiled in a single step, without intermediate linking.
+    This makes incremental development much slower for large programs but
+    enables far more optimization opportunities. In the future, an option should
+    be added for incremental compilation during edit-compile-test cycles.
+  * Interfaces are always represented as a ``{typecode, value}`` pair. `Unlike
+    Go <https://research.swtch.com/interfaces>`_, TinyGo will not precompute a
+    list of function pointers for fast interface method calls. Instead, all
+    interface method calls are looked up where they are used. This may sound
+    expensive, but it avoids memory allocation at interface creation.
+  * Global variables are computed during compilation whenever possible (unlike
+    Go, which does not have the equivalent of a ``.data`` section). This is an
+    important optimization for several reasons:
+      * Startup time is reduced. This is nice, but not the main reason.
+      * Initializing globals by copying the initial data from flash to RAM costs
+        much less flash space as only the actual data needs to be stored,
+        instead of all instructions to initialize these globals.
+      * Data can often be statically allocated instead of dynamically allocated
+        at startup.
+      * Dead globals are trivially optimized away by LLVM.
+      * Constant globals are trivially recognized by LLVM and marked
+        ``constant``. This makes sure they can be stored in flash instead of
+        RAM.
+      * Global constants are useful for constant propagation and thus for dead
+        code elimination (like an ``if`` that depends on a global variable).

 into object code. It can then be emitted directly to a file (for linking in a
 different build system), or it can be linked directly or even be flashed to a
 target by TinyGo (using external tools under the hood).
