Hello
A simple thing I stumbled across:
int main()
{
import std.stdio;
import std.range;
int[] d;
d ~= 10;
d ~= 20;
d.put(5);
writeln(d);
return 0;
}
Appenders work fine as output ranges, but arrays do not. The
above code prints "20" (ie the 10 is removed). Is "put" not
supposed to mean "append one element"?
Further, while the following compiles fine but runs really odd,
the following does not compile:
int main()
{
import std.stdio;
import std.range;
char[] c;
c ~= 'a';
c ~= 'b';
c.put('c');
writeln(c);
return 0;
}
C:\dmd\src\phobos\std\range.d(9,9): Error: static assert "Cannot
put a char into a char[]." (Test)
I am puzzled by
1) Why I cannot put a char into a char[] (even though I can
totally append them)
2) Why put removes elements from arrays
Hopefully somebody can help me clear my confusion about this (yes
in the meantime I can just use Appenders, but you know, still
wondering).
