I realize now that there is clearly no standard definition of "strongly typed".

For me it related to type casting pointers.

In "Weakly Typed" C/C++...

Foo f;
Foo *pf = &f;
Bar *pb = (Bar*) pf;
Bar& b = *pf;

Here, f points to a piece of memory it will treat as if it was in the structure of a Foo. b points to *the same* piece of memory and instead it will treat as if it was in the structure of a Bar. Foo and Bar may have totally unrelated structures. This is what I was thinking of in terms of weak typing.

I thought you couldn't do that in Perl - hence I called in strongly typed.

(It looks like you might be able to something similiar with the pack/unpack magic mentioned above - although it is certainly not a common practice.)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
