I found a few issues:
* Line 803. There's a typo in the code snippet. It should be "struct
Point(T)" instead of "struct(T) Point". Unless this is some pre 2006
template syntax I'm not aware of.
* Lines 810-811. The parentheses less template instantiation syntax is a
D2 feature. This has been explicitly noted for other D2 features
* Lines 983-1014. The "mixin template" syntax is D2 only, which has has
been explicitly noted for other D2 features.
* Lines 1036-1039. String mixins is a feature that exists in D1 as well.
During the D1 to D2 transition it was common to use a string mixin and a
version statement to either mix in D1 code or D2 code for code bases
that wanted to be compatible with both. It was necessary to use a string
mixin in cases where the D2 code was not syntactically valid in D1.
I've verified this with a D1 compiler.
