* As a consequence, trying to call or goto a non-routine-typed symbol
is now an analysis error, not a syntax error.
* Deprecated `routine foo ...` syntax has been removed.
* Split TODO off into own file.
* `sixtypical` no longer writes the compiled binary to standard

**SixtyPical** is a low-level programming language with advanced
static analysis. Many of its primitive instructions resemble
those of the 6502 CPU — in fact it is intended to be compiled to
6502 machine code — but along with these are constructs which
ease structuring and analysizing the code.
SixtyPical aims to fill this niche:
6502 machine code — but along with these instructions are
constructs which ease structuring and analyzing the code. The
language aims to fill this niche:
* You'd use assembly, but you don't want to spend hours
debugging (say) a memory overrun that happened because of a
ridiculous silly error.
* You'd use C, but you don't want the overhead of compiler-added
code to manage the stack and registers.
* You'd use C or some other "high-level" language, but you don't
want the extra overhead added by the compiler to manage the
stack and registers.
SixtyPical gives the programmer a coding regimen on par with assembly
language in terms of size and hands-on-ness, but also able to catch
