Is your feature request related to a problem?

Similar to null-safe member accesses, we might want to call an expression if it is not null and return null otherwise.

Desired solution

  • Null-safe calls, with a syntax similar to TypeScript: a?().
  • Move isNullSafe from SdsMemberAccess to SdsChainedExpression
  • Apply the current checks involving isNullSafe to all SdsChainedExpression
