Wow, this is fantastic. Below are a few things I have on my own "cheat
sheet" that aren't on the refcard. Somebody holler if any of these are
bogus.

Virtual methods:
scalar.chunk(size) # negative size chunks from R to L
scalar.list # treat as a single-item list
scalar.size # returns "1", as if it was single-item list

hash.exists(key) # does key exist?
hash.defined(key) # same as hash.key.defined?
hash.size # number of pairs
hash.item(key) # same as hash.key (when key is expression)
hash.list # returns [ key1, val1, key2, val2, ... ]

list.grep(re) # list of items matching re
list.unique # list of unique elements, retains order
list.merge(list1, [list2, ...] ) # combines all lists into new one
list.slice(from, to) # returns subset
list.splice(offset, len, [list]) # modifies list

Special variable "loop" methods:
size, index, prev, next

Filters:
html_entity # fix all entites, not just < and > (which is what "html"
does)
html_line_break # convert "newline" chars to <br>
ucfirst
lcfirst

Also, some suggestions regarding directive syntax:
[% INSERT filename %] # I don't think you can "insert" a block
[% MACRO name[(varlist)] directive %] # optional "prototype" syntax for
predeclaring variables to be localized in param list
[% USE [var =3D] plugin[(params}] %] # optionally assign return value to =
a
variable
Maybe the [var =3D value ...] option could be added to the PROCESS and
WRAPPER directives?

Thanks for sharing this with us, it's a big help!
Jason
