Tried to compile
https://github.com/CyberShadow/DustMite/tree/bf937e91c7a768b4ecc3681c655a269e0a8d3dd8

And here's the completely weird result:
$ dmd -c dustmite.d
$ dmd -c dsplit.d
$ dmd -c dustmite.d dsplit.d
$ dmd -c dsplit.d  dustmite.d
dustmite.d(520): Error: template std.algorithm.canFind(alias pred = "a ==
b",Range,V) if (is(typeof(find!(pred)(range,value)))) does not match any
function template declaration
dustmite.d(520): Error: template std.algorithm.canFind(alias pred = "a ==
b",Range,V) if (is(typeof(find!(pred)(range,value)))) cannot deduce template
function from argument types !(__dgliteral7)(Result)
dustmite.d(520): Error: template instance canFind!(__dgliteral7) errors
instantiating template

I've tried my best to reduce this, but couldn't get anywhere cause there's no
help at all why the constraint failed.
DustMite itself couldn't help either since a proper test command would be
needed or it will simply reduce it to crap with a canFind(a) somewhere.
