b0a72ee06a Be more careful when parsing block calls
Previously, the parser would try to interpret this as a block call:

    if true {} // No semicolon
    {|i, am, a, block|};

Which, though unlikely, might come up in practice.

7114702496 Change the way block calls are parsed, mark them as block-calls.
This makes it possible to omit the semicolon after the block, and will
cause the pretty-printer to properly print such calls (if
pretty-printing of blocks wasn't so broken). Block calls (with the
block outside of the parentheses) can now only occur at statement
level, and their value can not be used. When calling a block-style
function that returns a useful value, the block must be put insde the
parentheses.

0714bb5f7d Fix the problem with check-fast randomly failing
Trans has been assuming that tag node id's are unique across crates and they
are not so, depending on which way the wind is blowing, it would choose to use
a crate-local tag variant instead of the correct one from std.

No test case since I can't come up with a reliable one that compiles in a
reasonable amount of time.

33167f7dec Adjust function signatures to allow for vecs being immediate
Some code was relying on vectors being implicitly by-reference (as
non-immediate value). This adds the necessary &&-sigils.

f26e770745 Make 1-1 parse again
Issue #954

This is not a very elegant fix -- we should probably do something with
constant folding to handle negative-int alt patterns in the future.

f375391cb6 Patch to error instead of crashing when parsing unmatched double quotes
Patch to error and fail instead of using all available memory
then crashing to detect the error condition of an unmatched
double quote before the end of a file.

I couldn't get it to show nice error messages, so this may not be
the ideal fix.

A test case for this situation has also been added.

b1bf9ef5ae Break fold's circular reference during unwinding
This converts the AST fold into a resource that breaks it's own circular
reference (just a temporary workaround until GC), so that failure during fold
will unwind correctly.

d7587c1eda Change convention for specifying referenced argument
It is now 1-based, rather than 0 based. (Seems more natural, and allows 0 to
be used to refer to self and maybe to closure.)

Also allows non-referenced args to be implicitly copied again.
