StingType 1.0: the freeze, and what's left

GSTC is at 0.95 (prerelease). From here to 1.0 the language is frozen: no syntax or meaning changes, only fixes. A program that builds with 0.95 and doesn't rely on a bug will build and behave the same with 1.0 and every 1.x.

Frozen (SPEC.md is the contract)

• Syntax: the reserved words (SPEC 1.1), word-closed blocks (end, endfn, endstruct ...), no braces, // comments.
• Types: the integer, float, bool, str, pointer, array, slice, function, struct, union, enum and generic forms of SPEC 2, with no implicit conversions.
• Checked arithmetic: + - *, division, shifts, indexing and casts stop the program with a runtime error when they go wrong; wrap_add/wrap_sub/wrap_mul and checked_* are the ways around.
• Memory: no garbage collector; new results and alloc are yours to free; freeing twice is a runtime error.
• Libraries: include "x.sth" / as name; one file has one copy however many names include it.
• Generics: inference from arguments, then from where the result goes; explicit f<T>(...).
• Function values: real machine addresses; any parameter type, a number/bool/pointer/function result.
• Errors: the wording and shape of compile errors and runtime errors (tools may rely on file:line:col and runtime error:).

Not frozen (may grow in 1.x, without breaking programs)

• New library functions and new libraries.
• New targets, and the code gstc generates (faster, same behavior).
• New warnings (a warning never stops a build).
• New compiler options.
