if "0":print("foo")         # foo

if"0":print("foo")          # SyntaxError: invalid character '▶' (U+25B6)

if"abcdef":print("foo")     # SyntaxError: invalid character '▶' (U+25B6)

if"0":
  print("foo")              # SyntaxError: invalid character '▶' (U+25B6)

if"":print("foo")           # (this one's fine, yielding no output)

The full error for all of those is

File "<string>", line 1
   if ▶0⏹:  #1: if"0":print("foo")
      ^
SyntaxError: invalid character '▶' (U+25B6)```

Notably, the referenced transpiled code is independent of the source string.

See Coconut's
[documentation](http://coconut.readthedocs.io/en/develop/DOCS.html) for
more information on all of the features listed below.

Language changes:
* #814: Changes to statement lambda scoping rules, including capturing
names introduced in the surrounding expression.
* #618: Changes to handling of pattern-matching function defaults
including support for e.g. `match def f(x, y=x) = (x, y)`.
* #809: New array concatenation implicit partials (e.g. `[. ; a]`).
* #823: New `(x := .)` implicit partial syntax (only available in
pipes).
* #807: New `lift_apart` built-in combinator.
* #813: New `(if)` operator function.
* #826 (thanks @JayXon!): Better universalization and `fmap` support for
`bytes` and `bytearray`.
* #816: Support for `xarray` to match existing `numpy`/`pandas` support.
* #817: New `to` argument to `all_equal`.
* #821 (thanks @GolfingSuccess!): Expanded implicit function application
syntax to support string literal methods.

Compiler changes:
* #799: `coconut-run` and `coconut --run` now work on packages rather
than just files.
* #812: Better formatting of Coconut exceptions.

Bugfixes:
* #810: Fixed an issue compiling certain syntax constructs in the
Coconut Jupyter kernel.
* #818, #825 (thanks @kg583, @dokutan!): Fixed parsing of different
Unicode line break characters.
* #822 (thanks @JayXon!): Fixed parsing of Unicode backward pipe
operators.
* #819, #820 (thanks @kg583!): Fixed some incompatibilities between
Python and Coconut syntax.
