Is this a bug?

The following fails to compile with an 'cannot deduce function 
from argument types' error. When using an array of something 
other than TypeInfo_Class everything works as expected.

void main()
{
	import std.algorithm.mutation : remove;
	
	TypeInfo_Class[] arr;
	TypeInfo_Class c;
	arr = arr.remove!(a => a is c);
}
