Thanks for a wonder article.

Thanks! Two improvements:

- People outside of the D (and C++) community may not know who "Andrei" is.

- Assuming they are line numbers, the 2 and 3 below should be 3 and 4:

    (i < 3 || _d_assertp(TMP, 2))
    (j & 1 || _d_assertp(TMP, 3))

It doesn't mention that MS-COFF is available for 32bit as well.

In case strings hash to the same value, the linkers (ld and ms) have an option to detect discrepancy in content.
