In std.json is a function getchar() with this signature:

dchar getChar(bool SkipWhitespace = false);

But it is called differently:

getChar(); // obviously SkipWhitespace = true;

getChar!true(); // probably getchar(true)

What is the reason for the different notation ?

It looks like the signature (line 115) is:
dchar getChar(bool SkipWhitespace = false)()

Note the extra set of parens at the end, making the bool a 
template parameter.

That 'false' up there is the default value of SkipWhitespace.

 But it is called differently:

 getChar(); // obviously SkipWhitespace = true;

No, in that case SkipWhitespace==true.

 getChar!true(); // probably getchar(true)

The same thing; just being explicit.

Aside: bool parameters (regular or template) hurt readability. It would 
be better to have defined a type similar to std.stdio.KeepTerminator and 
its use with byLine():

I said "No" but kept your value. :) I meant "No, in that case 
SkipWhiteSpace==false."

I see. On the other hand: For an internal function like getChar()()
the implementation seem so be a bit to intricate. But for a public
API certainly preferable.
