Hi All,
Not to beat a dead horse, but Perl 6's docs are
miserably hard to understand.
Here is a comparison of Perl 5's perldocs and Perl 6's
docs:
Perl 5:
$ perldoc -f index
index STR,SUBSTR,POSITION
index STR,SUBSTR
The index function searches for one string within another,
but without the wildcard-like behavior of a full regular-
expression pattern match. It returns the position of
the first occurrence of SUBSTR in STR at or after POSITION.
If POSITION is omitted, starts searching from the beginning
of the string. POSITION before the beginning of the string
or after its end is treated as if it were the beginning
or the end, respectively. POSITION and the return value
are based at zero. If the substring is not found, "index"
returns -1.
Perl 6:
https://docs.perl6.org/routine/index
Documentation for sub index assembled from the following types:
class Cool
From Cool
(Cool) routine index
Defined as:
multi sub index(Str(Cool) $s, Str:D $needle, Int(Cool) $startpos
= 0 --> Int)
multi method index(Str(Cool) $needle, Int(Cool) $startpos = 0 --> Int)
Coerces the first two arguments (in method form, also counting
the invocant) to Str, and searches for $needle in the string
starting from $startpos. It returns the offset into the string
where $needle was found, and an undefined value if it was not
found.
See the documentation in type Str for examples.
"Cources"??? Seriously:
https://www.merriam-webster.com/dictionary/coerce
Definition of coerce coerced; coercing
transitive verb
1 : to compel to an act or choice
was coerced into agreeing
abusers who coerce their victims into silence
2 : to achieve by force or threat
coerce compliance
coerce obedience
3 : to restrain or dominate by force
And what the heck is a "multi sub" and a "multi method" anyway?
AND WHY DO I EVEN CARE? I just what to know how to use the
stinking thing! Geepers Creapers !!! (I am trying to avoid
swearing.)
Perl 5's perldoc just tells you what you need to know to use the
stinker. It is concise and to the point. Perl 6 is a nightmare
to understand.
Thank for putting up with my frustration.
