No. I cannot say that.
Since this is not a full port of renrem in C++ to D. It was just

The question is, what value do you want `index` to have when
I have a line of code that uses "to" function in std.conv for a

When the user_apply[ 4 ] has value, there is no problem; but when
it is empty: ""
it throws an ConvException exception and I want to avoid this
exception.
