Just a little too much complexity, for not enough benefit.
The POD for this change:
Looks good.
For legacy the old syntax #CONDITIONED_LINE(var): and
#INVERSE_CONDITIONED_LINE(var): is also supported.
Mention that this syntax will be deprecated.
For lispers the well-known reader-macro syntax #+(and key1 (not key2)):
is also supported, #+ #- with and, or and not, or being the default
for multiple keys without operator. But note the ending C<:>.
This syntax is not supported. The primary reason for rejecting the
syntax is because it's too much of a burden on maintainers. If we keep
the feature someone will certainly use it, and some poor P-language
programmer is going to get stuck trying to decipher it.
* or a key=value expression, which checks for the config key,
Note that values may contain no spaces here. Quotes in values
are not supported.
Seems like a sensible addition, though very limited. Make it '=='
instead of '='.
A key must only consist of word characters, and is checked
case-sensitively against the config key or the platform name.
Explicitly say what you mean by "word characters", because different
languages treat different characters as word forming. If you mean A-Z,
a-z, and 0-9, say so.
