I am quite confused by the following exception during dub

Performing "debug" build using ldc2 for x86_64.
demo ~master: building configuration "application"...
demo.d(221,20): Error: template object.get cannot deduce

The code that causes it:
"""
void main(string[] args) {
double[string] scores = calculateScores("test.txt");
double score = scores.get("hello", 0.0); // <-- exception
}
"""
It works if I just do "double score = scores["hello"];"
Both dmd and ldc2 throw this exception.
Is it a bug?
Are you sure the error is on the line you indicated? The error
message
claims that your argument types are (double[string], string,
string),
but your code clearly has argument types (double[sting], string,
double). Are you sure dub is compiling the source file(s) you
think
it's compiling? Which source file(s) are shown by `dub -v`?

It also says line 221. In which case he should be able to track
it down to line 221 and see where the error is.
