Perl 5 parses this as `($x) ? (@$a = ()) : ($b = [])`, where each branch is an independent assignment expression. PerlOnJava's compile-time `LValueVisitor` (Phase 4.7) correctly classifies assignment branches as `ASSIGN_SCALAR`, but the **JVM backend code generator** emits incorrect code for the runtime ternary-as-lvalue path when the condition is non-constant. +Expressions like `($x) ? @$a = () : $b = []` triggered "Modification of a read-only value attempted" at runtime. Perl 5 parses this as `($x ? (@$a = ()) : $b) = []`, where the true branch is a LIST assignment expression. -**Root cause**: When the ternary condition is non-constant (e.g., `$x`, `wantarray`), the emitter generates bytecode that evaluates both branches and selects the result — but the selected value is not returned as a modifiable lvalue. The assignment to the "winning" branch's target fails because the emitter wraps the result in a read-only temporary. Constant-folded cases (`1 ? @rv = eval $src : $rv[0]`) work correctly because only one branch is emitted. +**Root cause**: LIST assignments in scalar context return cached `RuntimeScalarReadOnly` values (e.g., the element count 0). When the ternary stored this in a spill slot and the outer assignment tried to `.set()` on it, `RuntimeBaseProxy.set()` called `vivify()` → `RuntimeScalarReadOnly.vivify()` threw the error. -**What's needed to fix**: -- In the JVM backend emitter (likely `EmitOperator.java` or `EmitAssignment.java`), fix the ternary-as-lvalue code path to emit proper lvalue references for both branches -- The emitter should generate a conditional jump that executes the selected branch's assignment in place, rather than evaluating both branches and selecting a result -- Reference: Perl 5's `pp_cond_expr` in `pp_ctl.c` — the ternary simply jumps to the selected branch, which then evaluates (including any assignments) and returns its result -- Alternatively, detect ternary expressions where both branches are complete assignments (not lvalue targets) and compile them as `if`/`else` instead of ternary-as-lvalue +**Fix**: In `EmitVariable.handleAssignOperator()`, detect when the LHS ternary has LIST assignment branches (via `LValueVisitor.getContext()`). For those branches, emit the inner assignment in void context (side effects only) and use the outer RHS as the result. Non-LIST-assignment branches (including scalar assignments like `$c = 100` which return the writable target variable) still get the outer assignment applied normally as lvalue targets. -**Impact**: Affects real DBI's `execute_for_fetch` implementation (worked around with if/else in our DBI.pm), Class::Accessor::Grouped patterns, and potentially other CPAN code using this idiom. +**Key distinction**: Scalar assignments (`$a = 1`) return the variable itself (writable lvalue).
