# A map from type name to type letter. We use this map for two reasons:
|
|
# 1. We want the debugging stuff in the source code to be as unobtrusive as
|
|
# possible, which means as compact as possible.
|
|
# 2. It's easier (faster) to parse these one and two-letter types in the C
|
|
# functions that display debugging results.
|
|
#
|
|
# All type strings are one or two characters. One-character strings
|
|
# are always lower case and should be used for common types.
|
|
# Two-character strings begin with an upper-case letter which is
|
|
# usually the same as the package name.
