I missed some functionality in std.algorithm, so i decided to use
findSplitBefore for my purpose.

Here is the code:

Unfortunately, ignoring second variable in pred, results in compilation error
like this:

/opt/compilers/dmd2/include/std/algorithm.d(4292): Error: template
std.algorithm.find matches more than one template declaration,
/opt/compilers/dmd2/include/std/algorithm.d(3504):find(alias pred = "a == b",
R, E)(R haystack, E needle) if (isInputRange!(R) &&
is(typeof(binaryFun!(pred)(haystack.front, needle)) : bool)) and
/opt/compilers/dmd2/include/std/algorithm.d(3555):find(alias pred = "a == b",
R1, R2)(R1 haystack, R2 needle) if (isForwardRange!(R1) && isForwardRange!(R2)
&& is(typeof(binaryFun!(pred)(haystack.front, needle.front)) : bool) &&
!isRandomAccessRange!(R1))
/opt/compilers/dmd2/include/std/range.d(611): Error: static assert  "Cannot put
a char[] into a Appender!(string)"
