Deviations from the r5rs Standard

Although husk closely follows R⁵RS, there are still differences between our implementation and the published standard. This page is a collaborative effort to identify and document any of these differences.

Confirmed

• Identifiers are case-sensitive
• cons cells store values as opposed to pointers, so it is not possible to construct circular lists, and set-car! / set-cdr! are restricted to only work directly on variables.

Questionable

• Equality procedures should take memory location into account (see Issue 85)
