- Check `method.isConst()` every time a method is resolved
instead of once per node instance (`isConstChecked`).
Given that `needsConst` only happens in very specific circumstances,
I'm not entirely sure if every resolved method needs to be checked.
However, it's a cleaner solution in any case, and `method.isConst()`
is a fast check that also never happens on the `evalCached` fast path.
- Do not check for const-ness of `FunctionN.apply` methods.
This check seems unnecessary and would always fail if triggered.
(According to `base.pkl`, none of the `FunctionN.apply` methods is const.)
- Remove unnecessary Truffle boundaries for modifier checks,
which are just bitwise operations.
- Improve const/import docs.
Changes include:
1. Spelling correction addressing #401
2. Grammer and punctuation corrections.
3. Rephrasing of some harder-to-read sentences. Most are simple one or two-word additions to make reading less jarring.
4. Changed hyphenation occurrences that included – rather than a regular hyphen-dash.
