No, not really. ITL tag names have always been either hyphen(-) or
underscore(_), all the way back from Minivend 2.0. It gets canonicalized
when parsed.

Don't mistake that for embedded Perl, where you must always use
underscore; remember that a hyphen can not be in  a valid function call
name, and that hash parameters using hyphens must be quoted.

In other words:

GOOD:  [user-tag  some-param="foo"]
FINE:  [user-tag  some_param="foo"]
OK:    [user_tag  some_param="foo"]
GOOD:  $Tag->user_tag({ some_param => 'foo' });

NONO:  $Tag->user-tag({ some_param => 'foo' }); ## Perl syntax error
NONO:  $Tag->user_tag({ some-param => 'foo' }); ## Option will never be seen

I like - for ITL tags, both for parms and tags -- it seems easier to read.
Of course in embedded Perl, you have to use _.
