    But not to people first learning the language!!

    You can verify this by giving this test to non-Ada programmers:

    ----------------------------------------------------------
    The following is a list of keywords in one or more unknown 
    programming languages.  Please write down your best guess
    as to the purpose of each keyword listed.

       1) pragma

       2) Compiler:

    ----------------------------------------------------------

    The responses will be, respectively,

       1) Don't know.

       2) This looks like a compiler directive.

    ----------------------------------------------------------

    Programming languages would come much more naturally if this
    sort of testing for user-friendliness were performed more often.

    Overall, Ada did a fine job of selecting user-friendly keywords, 
    but pragma is a case in which it just didn't happen.  Closer
    attention to this factor would reduce psychological barriers to
    learning Ada, thus promoting its widespread use and acceptance.
