No it's not:

import std.stdio;

struct foo {
	size_t	_a;

	this(const size_t b) const {
		this._a = b;
	}
}

class bar {
	size_t	_a;

	this(const size_t b) const {
		this._a = b;
	}
}

void main() {
	const a = new foo(42);
	const b = new bar(42);
	writefln("a._a: %d\n", a._a);
	writefln("b._a: %d\n", b._a);
}

works as expected. dmd v2.058
