Generic functions with angle-bracket type and magnitudo parameters.

# =============================================================================
# generic — Generic functions with angle-bracket type and magnitudo parameters
# =============================================================================
#
# What this teaches:
#   • Generic functions with angle-bracket type and magnitudo parameters.
#   • Related keywords: functio, genus, magnitudo
#
# Common mistakes:
#   • Type parameter not satisfying bounds — generic parameters must meet any constraints declared on the generic function or genus.
#
# See also: functio, genus, magnitudo
# =============================================================================

# Generic functions with angle-bracket type parameters
#
# Type and size parameters appear in `<...>` before value parameters.
#
# GRAMMAR:
#   funcDecl :← 'functio' ident genericParams? '(' valueParams ')' ...
#   genericParams :← '<' (ident | 'magnitudo' ident) (',' (ident | 'magnitudo' ident))* '>'
#
# EXPECTED OUTPUT:
#   generic function signatures paratae

# BACKEND: Generic call codegen gap on Rust (`T: Clone`; whitelist: generic/generic.fab).
# Call sites are deferred in this smoke exemplar.
