# What this teaches:
#   • Starts a scoped do-while style loop.

#
# Common mistakes:
#   • Using `จับ` on a non-`ทำ` block — `จับ` only attaches to `ทำ` statements, not arbitrary blocks.

# =============================================================================

# ทำ — try block with จับ error handler
#
# ทำ { <body> }
# จับ err { <handler> }
#
# GRAMMAR:
#   facStmt :← 'ทำ' block 'จับ' ident block
#
# EXPECTED OUTPUT:
#   none — success path then simulated failure on attempt 2
#
# BACKEND:
#   Rust/Go: ทำ/cape not yet emitted — compile-only smoke.
