Re: Prolegemona To A Future Scripting Language: Game Of Life In Perl 6by TheDamian (Priest)

That's a great effort, especially without a compiler. Here are a few corrections and some more "idiomatic" solutions.
Comments in bold italics explain corrections on the previous line.
# Indirect object syntax requires colon after invocant
# Argumentless &loop is cleaner that &while for infinite loops
# Bit is potentially much smaller than Int for 1/0 values
# BUILD is the object initializer.
# CREATE is something else entirely (see Apocalypse 12 ;-)
# Setting default value to 0 reduces initialization costs
# Can't declare variably dimensioned array as attribute.
# Have to declare it when dimension known (i.e. in
# constructor) and then bind it to attribute
# Utility sub to factor out repetitive 2D iterations
# Prefer &for over &loop when possible (e.g. here)
# Pass &iterate a block with placeholders for $x and $y
# STDIN is now $*IN
Update: Fixed display method (thanks jkahn)
