Soft keywords

This is a list of keywords that seem to be possible to make "soft".

"soft" keyword means that it is possible to use it as an identifier in most places, anyway they're reserved for certain situations. Sometimes, "soft" keywords are not matched as keywords unless syntax is proper, these soft-keywords are soften.

For now, I'll leave all keywords hard, as syntax often changes, thus there would be some conflicts.

init

init keyword is used for initializers (constructors), and syntax is following:

init() {
    // ...
}

Same as function item but without func keyword. Absence of func keyword gives us opportunity to softly check for init keyword. init is an item, thus only appears on item-only level (in structures), so it is possible to check if it's an initializer but not a function call.

Problems

• Requires context-dependent parsing, as we need to check for init appearance only inside struct (maybe trait) but not in func (expression context)
