# Proof of concept to create a class from a string instead of writing it to a
|
||
|
|
# file and then loading it.
|
||
|
|
#
|
||
|
|
# I hope to use this to create doubles in the future, though it will make
|
||
|
|
# debugging the generated code a little harder, it always bothered me that I
|
||
|
|
# was writing and reading files. It's slower and wastes cycles on the HD.
|
||
|
|
# Probably shouldn't bother me that much, but it does..
