Method call syntax with templates

[def-]

I don't know if method call syntax should work with templates, but right now the error is not very clear:

type Length = distinct float
const meter = Length(1.0)

template metricPrefix(unit: expr, prefix: expr, factor: expr): stmt =
  const `prefix unit`* {.inject.} = factor

# Doesn't work
meter.metricPrefix(milli, 1e-3)
# Works
#metricPrefix(meter, milli, 1e-3)

minimal.nim(8, 5) Info: instantiation from here
minimal.nim(5, 8) Error: identifier expected, but found '`milli 1.0000000000000000e+00`'
